I'm pretty sure it's an M22, it's noisy and allot of fun to drive lol. I read somewhere people used to beef up M21 with M22 internals? As for the rear gears i'm not sure but i know it was geared for launch, 3.73s are what i had in mind. The cars a daily driver for the summer, what makes it so bad for a daily? J/w
I checked ebay looking for the right parts and turned up allot, thanks. Joe, yeah I've got a set of 79' trans am brackets, and allot of other parts for one of those but i don't think any of it will bolt to this camaro except the mounts.
