Re: M20,M21,or M22?
I purchased an M-22 Supercase Muncie a couple of years ago for my current Biscayne. The main reason I went with it is because of all the cars I've owned in my life, I've never had one with a real Rockcrusher in it. That was a missing part of my life that needed fulfillment! Now.......I don't know how hard you have your heart set on a new Muncie, but I do know that the next transmission that I buy will be a Tremec TKO 600. It's got the lower First gear AND an Overdrive in Fifth. You can put a stock style shifter on them, they are very reasonably priced, and nobody but you knows that it's in there! I've just heard too many good things about those Tremecs and everybody seems to often say that it was the single best modification that they've ever done to their car. Not trying to talk you out of the Munice, just some food for thought.

Re: M20,M21,or M22?
If you have to have a Muncie, go with a set of M22W Italian gears.
With the right set of rear gears it's better on the street/highway but you still get the strength of a M22.

Besides I don't think the new Italian gear M22's whine like the old days. Tremec, used Jerico etc.

Re: M20,M21,or M22?
My M22 Italian gears did whine but not very loud.
I have done some research on the M22W gears and they are supposed to handle 600HP...I guess I'll find out when I use them!

Re: M20,M21,or M22?
I have 2 m22 one is from a 1970 camaro and its all original
with about 20 thousand miles on it. the other one is an m22 also but with a new italian input shaft and what a difference. My m22 thats in my L78 chevelle is not orig to the car and I have the real one on the shelf.This orig Camaro trany howls just like a 747 jet flying over your head at 50 feet.The other one with italian input shaft is no where near the same noise. LOOOOOOVe it!!! PJ
