What is an M29?

The mustang runs without a backseat because of an update/backdate allowance


The M29 was a T56 that had gearing that was "shorter" (similar to the C5 Z06 instead of the standard T56, but I believe it was slightly different gearing). It has a lower torque rating, but more "gear".

1993 Camaro/Firebird w/2.73 final drive "M28" 350ft lbs 3.36:1 2.07:1 1.35:1 1.00:1 0.80:1 0.62:1 reverse 3.28:1
1993 Camaro/Firebird w/3.23 final drive "M29" 400ft lbs 2.97:1 2.07:1 1.43:1 1.00:1 0.80:1 0.62:1 reverse 3.28:1
1998 Camaro/Firebird 450ft lbs 2.66:1 1.78:1 1.30:1 1.00:1 0.74:1 0.50:1 reverse 2.90:1

Right but that only works with an LT1/LT4


There are ways

Not without doing work to the trans that is illegal in ESP

You could get a trans rebuild and spec the other gears. Externally it would look the same. I have a rebuild TR6060 and I could have gotten the lower gears; but I kept the stock ratios. I guess you can get a good launch with the lower gears, usually good, but maybe you need to hit 3rd gear for a very fast course. At my region's airstrip location, I still don't even get to 3rd gear, but at top of 2nd a lot, but not sure that on slicks I'd need much more actual speed for Autocross.

Which would be blatant cheating

Yeah, unless it's a lump off a factory shelf with those ratios, you can't pick and choose what's inside it and stay in the letter of the rules. If there's no update/backdate transmission available like that, you can't do it. That's the way *SP rules are.

I'm leaning towards a FAST 102 instead of tjhe trans swap. M29 is possiboe but most likely not with the small clucth and would require fabrication on top of that. The manifikd seems likr a better long term investment with the eventual LS2 build for CP. I think I have one more year of ESP before making the jumo.
