427ci LS2 sleeved, dry sump oil pump, engine build & install, 69 Camaro

[DFRESH]

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.

Thanks 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.

Here is a shot of the "intake air temp" sensor in the air cleaner base




The bell housing for the T56 is being delivered tomorrow. This weekend I plan to start on the trans swap (muncie to T56 Mag)

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.







I used GM truck coils for this build. The truck coils have aluminum heat sinks to help dissipate heat.... a nice feature.






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.

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

Thanks Ron. It’s fun to try something different and I’m glad to share the info here. I couldn't be happier with the single plane set up on my LS engine, no regrets.

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.

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.

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

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.

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

Hi Dale. I'm actually installing a T56 Magnum into my '69 next month(on a BBC), so we're in the same boat. I have the transmission and the same bellhousing as yours sitting on my garage floor also. I went with a Speedtech crossmember and I'll be using a Centerforce DYAD clutch. I have the Keisler/Wilwood master cylinder and firewall mount. You can see pics of that in my build thread. I've been told that the GM collar and hydraulic throwout bearing will work fine for my application, similar to what you have. When you ordered your ZR-1 kit, did it have individual part numbers for the hydraulic throwout bearing and collar? If so, could you share them? If not, what was the part # on your clutch kit? Thanks in advance for anything you an share on that.

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.
