M22 transmissions

Probably the 70 and later 26 spine input, and larger output spline models.

With a fine spline input/output you get a larger minor diameter, which should make them more resistant to twisting.

The gears and shafts on those were pretty stout, the cases, on the other hand, generally were not. I remember a time when all the Muncie and T-10's I did 50% had issues with case cracks.

My tremec is not legal for the fast class so i am changing it for a m22. Just trying to figure out what one to use with around 500 to 550hp at the tires.

I would just use the Supercase and build from there. Or you could even find an iron T-10 case and build a pretty stout T10. The class allows use of different transmissions as long as they were made for a GM vehicle. One nice thing about the FAST class of racing is that the lack of traction definitely saves parts. Ed Cook's kid James grenaded the Hemi crash box I built for his RR, but that was attributed to driveshaft yoke failure. It's not likely that you would have any durability issues as long as you run the bias ply tire. Even less of a chance of trans failure with a "soft-lock" type clutdh that you would be wise to run.

Give me some details on the FAST build.

I just sold my combination that was in my car so i could build my car up just for this class. It was making 557 rwhp and was a blast to drive but i never raced it. This will give me a chance to do something different , meet new people and see some awesome cars. With no more races than there are i will have plenty of testing time.

Combo will start with a nice BB with aluminum heads and a m22 proshifted.

I wonder if anyone makes straight cut gears for the muncie? The result would be a more effecient trans with more whine.
