I'll plan to use the stock Tremec shifter for now.... maybe try the Blackjack later on after the fix. My Muncie trans always leaked oil and I want to get away from that. Yea I can't wait to get the new trans in. I ran about a dozen track days with the Muncie and never had any issues... the first time on the track with the new engine I seized up third gear on the main shaft... this caused the rear end to lock up at about 80 mph! Honestly I just don't trust the Muncie after that... time for some new technology. I can't wait for that first time behind the wheel with the new trans :D (ordered QT bell today) |
For my engine we went with a 150 Amp Powermaster alternator… a billet aluminum alternator mount, and a 3-1/2” diameter billet aluminum 6 rib drive pulley.
The stock pulley on the Powermaster alternator was 2” diameter. The engine builder changed the pulley from 2” diameter to 3-1/2” diameter so the alternator would run at the correct speed when I am running higher RPM’s on the track. He also provided a 2” diameter pulley and a smaller diameter serpentine belt set up for street only use. So far I have run the 3-1/2” diameter on the track and on the street with no issues. I did notice that when I’m in traffic on hot days with the electric fan running full time, the battery voltage drops slightly. Under normal driving conditions it's fine.

I have always had problems with the stock power steering pump boiling over when I do the HPDE events (makes a mess!!). For this build I upgraded to a KRC racing power steering pump and billet aluminum mount. The KRC pump has a 6-1/2” diameter pulley… my stock Chevy power steering pump had a 5-1/2” diameter pulley.
So far I have done one HPDE event with the KRC unit with no problems (no boil over). My educated guess is that the stock unit is not designed to run high RPM’s for extended periods. The speed of the pump is too fast and that creates extra heat. The KRC unit is better suited to running at higher RPM with the larger diameter pulley. This slows down the pump speed which helps to reduce power steering fluid temps. So far so good...no leaks the last time out. The power steering pump is mounted high on drivers side of engine. http://i1048.photobucket.com/albums/...psda8ef800.jpg http://i1048.photobucket.com/albums/...ps54c22e8c.jpg Here is a shot of the 6-1/2" diameter 6 rib KRC pulley. The mounting bracket was made by the engine builder. http://i1048.photobucket.com/albums/...ps62fdefeb.jpg |
Welcome to the site! Great car--and the motor sounds sweet---especially for an LS motor. I think you will find a more responsive audience here, especially since it's a 69 Camaro---we only have a few of those on this site.
Looking forward to more updates and some additional track photos when you have them. Doug |

Here is more detail on the 4-barrel TB set up. The throttle body is just an air valve on this set up. The fuel is injected into the intake ports on the heads through the injectors mounted on the base on the single plane intake. We used a FAST 4-barrel TB on a GM LS7 single plane intake. The butterfly's open inward on the primary and secondary side, and are manually controlled rather than drive by wire. The arm on the TB has multiple mounting positions so you can control how fast the butterfly's open. I built a custom throttle linkage setup that attaches to the stock Camaro accelerator pedal. This worked out well...the throttle has a good progressive feel and does not come on too fast and is totally adjustable. The FAST throttle body has a TPS (throttle position sensor) and IAC (idle air control) built in. We installed a MAP (manifold absolute pressure) sensor inside the single plane intake and an IAT (intake air temp) sensor in the air cleaner base. The engine is set up with a speed density tune. Homemade throttle return spring bracket mounts to the front two screws on the TB. http://i1048.photobucket.com/albums/...psd00e802d.jpg The homemade throttle linkage (red rod) connects to the stock Camaro gas pedal http://i1048.photobucket.com/albums/...ps8cc072fd.jpg "idle air control" on the left, "throttle position sensor" on the right http://i1048.photobucket.com/albums/...pse14d24b2.jpg Here is a shot of the "intake air temp" sensor in the air cleaner base http://i1048.photobucket.com/albums/...pse5bf4ade.jpg The bell housing for the T56 is being delivered tomorrow. This weekend I plan to start on the trans swap (muncie to T56 Mag) :cheers: |
We used FAST 58# injectors for the port fuel injection. The engine builder machined the GM LS7 intake to accept the injectors and made some custom mounts for the fuel rails. We found out later that GM sells a LS7 single plane intakes with the injector ports already machined. This would have saved some time if we had known.
http://i1048.photobucket.com/albums/...ps87e99356.jpg http://i1048.photobucket.com/albums/...ps8d02fe79.jpg I used GM truck coils for this build. The truck coils have aluminum heat sinks to help dissipate heat.... a nice feature. http://i1048.photobucket.com/albums/...psa45d3093.jpg http://i1048.photobucket.com/albums/...psf628e60b.jpg I made a custom bracket to mount the GM truck coils to the Katech valve covers. The brackets are thin gauge steel and were cut out on a laser and then formed... I plan to make a new set from aluminum and then either polish or have them anodized red to dress it up a little under the hood. http://i1048.photobucket.com/albums/...ps44118bab.jpg |
Dale thx for posting. Not much info out there on conventional intakes on an LS motor. I doubt you'll max out your inatke air requirements (KPI?) with that set up :thumbsup:

The LS style intakes work great... but the single planes also work well when set up with the right parts. No problem with air flow on this set up. |
T56 Magnum install
I started working on the transmission swap from the Muncie 4-speed to the T56 Magnum this past weekend. I have had a lot of issues with the Muncie lately and can't wait to get the new trans in (oil leaks & syncro problems)
I bought a kit from Hurst Driveline Conversions that included a T56 Magnum close ratio trans, cross member, speedo cable, and some wiring. When I bought the ZR1 clutch kit it came with the clutch, aluminum flywheel, and a GM hydraulic slave cylinder. TUET11009 Tremec trans http://i1048.photobucket.com/albums/...psd67d8571.jpg GM slave cylinder http://i1048.photobucket.com/albums/...ps86e50fcc.jpg Quick Time steel bell housing, Hurst cross member http://i1048.photobucket.com/albums/...ps3f244a34.jpg I'm planning to use a GM clutch master cylinder and a mounting bracket on the firewall. Not sure which GM clutch master to use? Also, I'm wondering what to do about the reverse lock out mechanism that is connected to the Muncie trans. The lockout is set up so that when you put the car in reverse and turn the key off, the steering wheel locks. Not sure how to handle this. Any help with these questions would be appreciated, Thanks :thumbsup: :lateral: |
Dale you're going to love that tranny!
Call Jim Goodlad @ Hurst Tech, he's the previous owner of the original company and a great guy. He should be able to give good honest guidance on the clutch master. He also own's a '69 Z28. :thumbsup: I don't have any trans lock-out connected and the column lock still functions. Here's a pic that shows the position of mine (original automatic car) in a position that works........at least when I shut the ignition down when the fire erupted I could still steer! http://photos.smugmug.com/photos/i-X...XSjWZSK-X2.jpg |
Very Nice Dale.

Thanks Sieg Here is a picture of my steering column lock tab and the rod that comes up from a pivot mount on the sub frame. Maybe I just disconnect the rod and then anchor the tab so it can't rotate. http://i1048.photobucket.com/albums/...ps3b1c8a43.jpg |
Looks like mine is higher than yours in that pic. Anchoring wouldn't hurt, I've never touched mine in 20+ years.......But my header bolts are safety wired! :sieg:
Experiment and see how it functions. :thumbsup: |
Sounds like a plan... Thanks Sieg :thumbsup:

The steering wheel lock is controlled by a pin that is actuated with the key.... so no worries about the tab on the steering column causing the steering wheel to lock. He did say that if the tab was in the wrong position it would prevent the key from turning to the off position. This guy really knows his stuff.... you're right. Also... Hurst has a hydraulic clutch kit for the 69 Camaro that has billet aluminum mounting bracket for the clutch master, and all hardware to do the swap from mechanical to hydraulic. Hurst has been great to deal with... kudos to them. Thanks for the tip Sieg :thumbsup: |
Cooling the engine
I’m taking a break from the transmission install… the temps have been below freezing all week (must be nice to live in California :relax: ). This weekend when temps warm up (40’s) I’ll pull the Muncie and get started on the swap to the T56 Magnum. Today I ordered the parts to do the swap from the stock Z-bar mechanical clutch linkage to a hydraulic set up.
For cooling the engine I used a single electric fan setup and a Be Cool 28” x 18” aluminum two core radiator. The fan is a Ford Lincoln Mark 8 type with an output somewhere around 3,500 to 4,000 CFM. I used the original 69 Camaro fan shroud that came with my car, and fabricated an adaptor bracket to mount the electric fan inside the stock shroud. This set up worked great… I drove the car this past summer in 100+ degree weather in traffic and never had any issues with over-heating. The Ford electric fan has an S-blade design and is super quiet… very nice. The fan is triggered to turn on at a pre-set temperature programmed into the GM ECM. http://i1048.photobucket.com/albums/...psbef33471.jpg http://i1048.photobucket.com/albums/...pscdc19930.jpg http://i1048.photobucket.com/albums/...psd3bffba3.jpg For a side project I made some aluminum billet wheel centers for my Vintage Wheel Works V-45’s. I didn’t like the tall plastic ones that came with the wheels. http://i1048.photobucket.com/albums/...ps5ae46265.jpg http://i1048.photobucket.com/albums/...pse46f4605.jpg I used stainless steel fasteners to attach the wheel centers... they need a little more polishing. http://i1048.photobucket.com/albums/...psdf29d6a5.jpg |
Here's another item that wouldn't hurt cooling, I'm ready to pull the trigger on one.
The other "trick" the Steilow use on Red Devil but not on Mayhem was this set up: http://www.techafx.com/content/1969-...nt-spoiler-kit I built my own, pics are buried somewhere in my thread. :D Did you make those centers or have them machined? Like the fan set-up :thumbsup: |
Quote:
I like the spoiler design... the open center would get more outside air moving through the engine compartment... good idea. I'll check back in your thread for the one you built. I made the centers myself... turned them on an engine lathe and then used a bandsaw to cut the outside shape... then filed and sanded the edges by hand. It took a lot of time to make 4 of them. I sit behind a computer all day so it's good to get out in the garage, work on the car and make some things :thumbsup: |

Old school fabrication is good therapy. Nice work! :thumbsup: |

I look forward to your write-up about this installation. I'll being doing a similar write-up so maybe we can compare notes and help each other out. |
I think I finally found the part number on that slave cylinder. It's 24237569. Not sure if you thought about this, but I've heard remote bleeder lines can be very helpful when dealing with these hydraulic setups. I found a few sources for these that plug into this particular slave cylinder in case you're interested:

Trans swap
:sieg: That's a nasty cut... I made it through the day with no wounds :)
Made a lot of progress today... but ran into some fitment issues installing the new trans. I started out by removing the driver and passenger seats and the center console. I wanted to be prepared in case I had to modify the tunnel. http://i1048.photobucket.com/albums/...ps4374738e.jpg Next I pulled out the driveline, crossmember, and the Hurst shifter. http://i1048.photobucket.com/albums/...psa0d6c1fd.jpg http://i1048.photobucket.com/albums/...ps265987c6.jpg This is a shot of the cutout as the car came from the factory. They used a torch to cut the hole for the shifter. The writing with the white marker was done on the assembly line. I bought this car 30 years ago from my parents neighbor who bought the car brand new. I was the first one to ever take the console off. http://i1048.photobucket.com/albums/...psdd18ff95.jpg Next I pulled the Muncie trans out. I use a transmission jack with a custom made wood support that keeps the transmission from rotating. I have taken this trans out so many times because of clutch problems, oil leaks, and syncro problems, that I rigged this up to make the job easier. http://i1048.photobucket.com/albums/...psf9416bcb.jpg http://i1048.photobucket.com/albums/...ps5bec3b86.jpg This is a Muncie trans with an Autogear Supercase. The Autogear case has needle bearing pivots for the shift linkage pivots, a thick cast iron mid-plate for extra bearing support, and a thicker casting in front for more bearing support. This case is designed to handle more HP than a stock Muncie. Unfortunately the internals failed this time around and I siezed up third gear on the main shaft the first time out on the track with the new engine. I have spent so much money modifying and fixing this trans that I could have paid for the new T56. Anyway... I am glad to finally have the new trans. It will be nice to have the new technology, crisp shifting, and the overdrive gears for some longer road trips in the future :D http://i1048.photobucket.com/albums/...psb0f47742.jpg Here is a shot of the bell housing... I lowered the engine down in the back and was able to reach all the fasteners to remove it. http://i1048.photobucket.com/albums/...psf0f46c1d.jpg This is a shot of the ZR1 Corvette clutch. http://i1048.photobucket.com/albums/...ps2a872e0f.jpg I have more coming on the problems with fitment :cheers: |
Yesterday I ran into problems installing the new transmision. The dimensions on the new set up do not match the old set up. The distance from the face of the bellhousing to the face of the throwout bearing are different by about 7/8". There is not enough clearance for the clutch to clear the new throwout bearing.
Here is a picture of the old set up with the mechanical throwout bearing http://i1048.photobucket.com/albums/...ps09c2ae09.jpg Here is the new set up with the hydraulic throwout bearing http://i1048.photobucket.com/albums/...ps81c5165f.jpg http://i1048.photobucket.com/albums/...ps6bbfd9a4.jpg Here is a picture from under the car that shows the depth of the clutch from the back of the engine to the tip of the fingers on the clutch. The measurement is about 4-1/8" http://i1048.photobucket.com/albums/...ps42d09ae1.jpg This is a picture from the face of the bellhousing to the face of the hydraulic throwout bearing pushed back as far as it goes. I'm not sure what to do now? Either the bellhousing has to be spaced out or I need a lower profile hydraulic throwout bearing. I'm not sure why the stack up didn't work. The throwout bearing in the kit was supposed to be sized to work with the ZR1 twin disc clutch. It seems like if I could space the bellhousing out about 7/8" this would solve the problem. Any thoughts or ideas on what to do would be appreciated, Thanks. http://i1048.photobucket.com/albums/...psa110c14f.jpg |
I re-positioned the Tremec shifter to the forward position... so I removed the shifter.
Now I can see how the aftermarket shifters that don't have any seals would leak oil. In the forward position the shifter is directly above the gear and would have a direct spray of oil. I'm suprised they would have designed and sold a shifter with no seal :headscratch: http://i1048.photobucket.com/albums/...ps1b562585.jpg Here is a shot of the Tremec shifter from underneath. This shifter has a nice designed oil seal. http://i1048.photobucket.com/albums/...psc2c609d4.jpg I went with the forward position so the shifter would fit through the console. http://i1048.photobucket.com/albums/...ps99c6c577.jpg |
I have a completely different clutch but this may be a solution
http://bowlertransmissions.com/p/440...ing-adjustable. I think if you start using spacers between the bell housing you may have pilot bearing issues. |
Dale,
Here's a couple hints on the stack issue: https://lateral-g.net/forums/show...&postcount=212 https://lateral-g.net/forums/show...&postcount=216 |
If you pull the TO bearing off, does the transmission install properly into the pilot bearing? I'm going with the DYAD clutch and I'm pretty sure the deck height for that clutch(crank to fingers) is about 3", so if you're ZR-1 clutch is about 4", I can see where you'd have that 7/8" clearance difference. It does appear in the links Sieg provided that that there is a bellhousing/trans spacer for your situation, but that pushes your transmission further back and could cause other fitment issues. Just more fun with putting these darn things together. Can't wait to try to put mine in soon.
|
I'm not sure if Mark built that spacer for Mayhem or how they handled the pilot bearing/input shaft depth issue. My guess is he'd help if asked.
|
This is getting a little confusing... but it looks like there is a solution to make the T56 Magnum transmission and ZR1 Twin Disc clutch fit properly using the GM hydraulic throwout bearing (pn:24237569) and the GM pilot bearing (pn:12557583).
Here is a picture of the set up on the bell housing with the Muncie transmission. This set up was installed in the car and worked perfectly. This is a picture of the relationship between the end of the input shaft on the transmission and the flange on the bell housing. The dimension is 3/16”… this is what worked. At this dimension the input shaft on the transmission slipped into the pilot bearing about 3/4". http://i1048.photobucket.com/albums/...ps892180d0.jpg Here is a picture of the new set up with the Quicktime LS bell housing and the T56 Magnum transmission. The dimension from the end of the input shaft on the transmission to the flange on the bell housing is ~ 1”. If I use the 0.850” thick spacer from D&D performance that Mark Stielow on Mayhem then everything works… the distance from the flange on the bell to the end of the transmission input shaft goes to ~ 3/16”. The input shaft from the T56 Magnum will be the correct length to fit into the pilot bearing, and the GM hydraulic throwout bearing will have exactly the right clearance in relation to the tip of the fingers on the ZR1 twin disc clutch. http://i1048.photobucket.com/albums/...ps05ed3ea7.jpg Each combination of parts always requires a little head scratching… but it looks like this solution will work. Chris, if your clutch is about 3" thick then you can use the same parts minus the 0.850" spacer, as long as there is no difference in the position of the pilot bearing between the Gen I and Gen IV engines. Thanks Tim & Scott :thumbsup: |
That is weird. Your LS bellhousing(RM-8020?) is supposed to have the same depth as mine(RM-6023) for my BBC, which would be 5.555 inches. However, I just went out into the garage and measured the depth on mine and it's exactly 6.0 inches. So I'd like to send a big shot out to Quicktime for providing incorrect specs on their bellhousing. As a result of this extra .445 inches of depth, the input shaft on mine only sticks out about 5/8" past the bellhousing, and it would only be about 1/4" when I add the engine plate. So that should be okay for me when I mate it to the engine and pilot bearing. If it's too long, I can file down the shaft slightly. However, for you, it seems like you'll need that spacer in between your transmission and bellhousing. Hope it's not too pricey and is readily available. If the shaft doesn't quite reach the pilot bearing, I believe there are 'extended' bearings.

I do have the Quicktime RM-8020 bellhousing and it measures 5.55”. If I can get the 0.850” spacer from D&D Performance then everything will fit together. The input shaft on the T56 will slip into the pilot bearing about ¾”. Hopefully I can get one…. I’ll find out tomorrow. I think I'll have to shift my engine forward about 1" now. Hopefully your install goes smoother. After that first drive with all the new stuff all the problems are forgotten... Good luck getting all your parts to fit together :thumbsup: http://i1048.photobucket.com/albums/...ps6829a3cf.jpg |
Today is a good day :thumbsup:
It's Friday... I have the next two days off... and the last of the parts I need to continue the T56 install showed up on the door step :D Today I received the billet aluminum spacer that goes in between the T56 Magnum and the Quick Time bell housing. This spacer was needed to allow for the extra thickness of the ZR-1 Twin disc clutch. The spacer has dowel pins and fit up perfectly to the QT bell and the T56 Mag trans. The spacer is 0.89" thick. I checked all the dimensions with the spacer installed, and the play between the clutch forks and the hydraulic throwout bearing is perfect... and the input shaft on the transmission will slide into the pilot bearing on the crank about 3/4". http://i1048.photobucket.com/albums/...ps59d26fe8.jpg The dowels pins align the spacer to the bell housing. The dowel pins on the transmission align with holes on the other side of the spacer. The spacer is designed to keep all of the parts in alignment. http://i1048.photobucket.com/albums/...psda2653c6.jpg http://i1048.photobucket.com/albums/...ps0af20982.jpg http://i1048.photobucket.com/albums/...ps986fcf84.jpg http://i1048.photobucket.com/albums/...ps26d7231f.jpg Here is a shot of the GM ZR-1 hydraulic throwout bearing with a remote bleeder (4ft long) attached. The guy that did all my plumbing for the dry sump pump made up the remote bleeder from parts. http://i1048.photobucket.com/albums/...pse7deba22.jpg Earlier in the week I received the kit to convert from the mechanical Z-Bar clutch set up to the Hydraulic clutch. http://i1048.photobucket.com/albums/...ps0cb54504.jpg The remaining issues to deal with will be the tunnel mods and cross member mods. The spacer will push the trans back an inch so I'm pretty sure the crossmember won't fit. :cheers: |
Looks like you're on a roll Dale! :woot: :woot: :G-Dub:
