Ok, you ain't leaving Mexico until you show me Badmotorfinger!

Or that bright :rofl: !!!

Oops -- It's Dave that's down there! I think "vacation" can also be called "drug mule"??


Race car parts are expensive.... gotta pay for 'em some how!! :rofl: :rofl:

Greg, you must be watching too many episodes of Locked up Abroad.

Matt

Mexican customs was a breeze upon re-entry.... :unibrow:

Letsa buya thea Italian gear seta! We makea the car plenty fasta!! :D

Naw, we gonna be taking this trans drama into a newer decade.... I'm all fed up with 40+ year old Muncie "technology"... there's prolly a good reason none of these other PT/track cars are running an old M21. :thumbsup:



And in other news... the owner 2 owners ago of my car tracked me down after seeing it in Camaro Performers covering the RTTC2 event. He was really happy to see the car again and we chatted about everything he did. He actually painted the car in 1999 when he was 15 in hid dad's paint shop. And he did the mini-tub job before there was the mini-tub kit everyone buys today. Wants to come see it in action on the track someday. :cheers:

I'm installing an M21 in my 68 - old skool drivetrain for the win! :_paranoid if it breaks, then the Italian gearset gets commissioned :thumbsup:

Cheers,
Mark

What is the purpose of the bar across the enginembay? Looks beautiful

Cool story. Must of made your day. :thumbsup:

Well I gave it plenty of chances but they just aren't happy with my motor and apparently shifting techniques. :lol:

I thought about the Italian gearsets and told Rich about them, but now I am just thinking something newer and beefier altogether... and different.

After 4 various Muncies in this car in less than 2 months, I'd say it's time to try something else!

It's a Monte Carlo bar that was custom fabbed by the shop the previous owner had do all the rollcage work. It ties in those forward down bars that keeps the frame and cage all rigid.

Yes that was a fun chat and gave me -- as resident one-liner Todd would say -- the warm and fuzzies inside. :D

^ Hey Dave - what's the deal w the italian gear sets? Never heard of them (nothing new there). Also, that was a very cool story of the prior owner. Maybe you and Rich can draft him into the pit crew? :cool:

Apparently this is a way to get some stronger gears in there. There was/is an Italian gear company who manufacturers stronger M22 gearsets with a greater level of detail (apparently) than what Muncie themselves did. I couldn't find a ton of solid details on them but did find several 4 speed/Muncie rebuilders/sellers who sell them for about $500-600 a set. But, if I am going to dump $1000+ into ANY tranny, I figure it not be a Muncie.... you can dress up a hooker with Gucci shoes and bag but she is still a hooker. :_paranoid

:lateral:

And my pit crew is getting kinda big then.... puts some more pressure on said driver to perform. :lol:

Yep. Just look at it as a $1000 discont on the new tranny...:thumbsup:

Haha, Zebras? How was that

I don't remember for sure but that sounds right! I didn't go -- only the pit crew went... I was not feeling 100% that weekend so I stayed at the hotel, another Rosamond treat. :lol:

Haha, right on! I used to be a Lancaster local, we would venture to rosemond for a good laugh now and then.:cheers:

Well I dig the car and the videos, if you ever need another pit crew member, I'd love to come drink some beers.:woot:

Well after a little hiatus and some time researching and sourcing parts, we are back at it. Took out the trans and clutch yesterday to make way for this new baby:

http://i236.photobucket.com/albums/f...8/DSCF3459.jpg

http://i236.photobucket.com/albums/f...8/DSCF3463.jpg

It's a Tex Racing (now G-Force) T101A 4 speed from a Nascar team. Can routinely pick these up with some race miles on them for about $1800-2200, but I found a gem with mostly fresh/new parts on craiglist for $1750 in the gear ratios I was looking for - very close to the M-21/M-22 ratios.

2.26 1st
1.54 2nd
1.29 3rd
1.1 4th

It's got dog rings so can't wait to do some clutchless shifting and left foot breaking on the road course. :thumbsup:

One of the reasons I liked this conversion is that it's nearly the same case size as the Muncies I'd been using, and the only things we think are needed for the swap are a clutch disc change (10 spline to 26), a Turbo 400/1310 yoke, and some tunnel mods to make room for the heim shift rods and bulkier Hurst Super Shifter.

Also cleaned up the dirty exhaust system a bit. A $5 can of Rustoleum goes a long way. :D

Dave -- great choice! That tranny is bad a** and perfect for your intended use. I can't wait to see it run...! :thumbsup:

P.S. next time let me play delivery driver :lol:

Bad ass, that will be a blast to row through the gears. Now that's a close ratio. Look at 2nd-4th.:faint:

Now you're talking!!

Ha, I didn't end up getting that one... this one came from back east.. but I do appreciate your "courier" offer Ron. :thumbsup: :D

Sweet find. My muncie also has the turbo 400 32 spline output shaft. You may need to shorten your drive shaft also. I'm pretty sure I have the drive shaft you need laying in my garage. Let me know if you want to give it a try.

That's pretty sweet Dave, that tranny is gonna be wicked, great find...exhaust is lookin' good also.

Thanks guys. I'm making the push to be Ron's Vice Presidential candidate. :lol:

man you need to get a T-56!!!!!! ive been watching your vids on youtube, really i like the video with the corvette. keep up the good driving

Very nice - and cheaper than buying a Muncie/Rockcrusher/Super case combo! :thumbsup:

Uh, you do know Ron does a background check, right?

http://i87.photobucket.com/albums/k1...8302796946.jpg




Nice tranny acquisition though. :D

I considered lots of trannies... T56, TKO, M-22 Rockcrusher, Jerico.... but this fit budget and size and is bulletproof pretty much.

Thanks, and that was fun trying to keep up with that Z06. He ditched me pretty quickly though. :D

Yes, the badass Autogear or other beefed up Muncies were all over $2000.

LOL... thanks.

We all got the skeletons in our closet. :_paranoid :lol:

Checking right now...:lol:

Dave, just a little warning given your penchant for going through transmissions - I've only ever driven one car with straight cut gears, but I was told to use the clutch as you normally would, because while the trans was designed to function without the clutch in the event of a mechanical failure, it was intended to be used with it. If I'm wrong though, and sound like an idiot, please correct me :lol:

Matt

Dave that T101 should serve you well, good choice!

Very nice Dave. Nice to see the updates for Badmotorfinger.:thumbsup:

NOW that's a real man's Trans.No girly tunner crap there.:thumbsup: :thumbsup: Frickin,awesome.:thumbsup: Scott

Hey Matt. I def have not authority to say you are wrong... or an idiot... :D
What I can say is I've spent the last couple months talking to all kinds of people on the subject of T101/Jerico dogbox trannies, and there were def mixed opinions on some subjects (using the clutch vs not, and clutch size/usage mainly). But most that I talked to who road raced -- and even 1 guy who built and maintained the T101A driveline for a Rusty Wallace Craftsman team for 8 years -- encouraged not using the clutch on the track.

Here is a video in a T101A thread on another forum I found, and what I will be trying to mimic on the track:






Oh, and since you mentioned I love to kill Muncies.... here is the current Muncie Graveyard at the shop. :)

http://i236.photobucket.com/albums/f...DSCF3473-1.jpg

Thanks fellers! :thumbsup:

No girly crap here Scott! I love it! HAHA! :rofl:

let me know if you would like to sell some of those muncies, I have some customers interested in 4 speed swaps.

That is quite the graveyard you've got over there. I'm just curious, but what is the logic behind the clutch/clutchless debate. I'd love to know a little more. I suppose the trans was designed around racing, seems like it was the right choice given what you do to the car, and probably won't be joining the Muncies any time soon, but I'm curious as to what maintenance is required. Do these last quite some time without a rebuild? I don't know much about the Jerico. I just know they're tried and true.

BTW, I think I know why you really went with this transmission. You don't have to heel-toe in your car anymore :lol:

Matt

I could be wrong.... but I don't think this gearbox is straight cut gears, it's dog change. Dog change is a different style of engagement (most manual's are synchro). Dog change are more widely spaced engagement teeth on the gear and selector hubs to help with shifting at high rpm's. Done correctly you can shift faster because you are matching the rpm's of the gears and you are not relying on the synchros to match rpms which takes time.

You can still miss shift and beat the dogs up, but they are thicker than the synchro teeth and can take some abuse. The dog teeth are back cut so when you are on power they are locked together. When you don't match rpm's correctly you damage the leading edge of the back cut which if it gets bad enough (effectively ruining the back cut) allows the dogs to slip apart causing the trans to slip out of gear.

Sounds like a sweet setup! ....did you get it from racingjunk? I was looking for more info on the trans and found a wanted ad for one there.

-Dave

That's a possibility. 2 of those are mine and 2 are Rich's. Actually only 1 has a broken gear. I'll talk it over with him.

First thing I can think of is less of an rpm drop by shifting without the clutch and just lifting off the gas quickly. Beyond that I am not sure. I plan to street drive it before Buttonwillow and will try both ways.

Maintenance -- again, different opinions, but they are all pretty similar. The thing is... most everyone is using these trans in very heavy duty racing environments i.e. oval track, 200-300 mile races, or regular track days. I foresee 4-6 track days per year for me for the next year or so I can be a little less aggressive on schedule I would think. Every single person I talked to says to use Mobil 1 synthetic 75-90. Check/change fluid every 1-2 races and service/refresh every 1-2 years (or 1500 race miles. Uh, that's a lot).

And what do you mean I don't have to heel-toe anymore? I never did before! :lol:



Thanks Dave. I did get a few emails from racingjunk guys but they were either overpriced or not what I was looking for. Found this one on Memphis craigslist. I searched wide and deep!

Looks like you are partially correct on the dog ring vs straight cut deal. A dog ring trans can have either helical gears or straight cut gears, or a combination. Nice little write up here:
