Hi, I'm new to the forum and need some advice. I have a 69 LM1 Camaro with 350 - turbo 350 auto trans that I would like to swap for a 4speed, Console car horseshoe shifter. The question is which 4 speed? I have contacted a few people in the industry some suggest the M20 wide ratio other suggest the M22 Close ratio. I have considered the tremec tko500 for the overdrive, but would like to keep the somewhat of the originality of the muncie trans.
I will be swapping the 350 engine 255hp for a 383 stroker with 525hp. also have 3.73 gears in the 12bolt.
Would I need to change the drive shaft and trans cross member with this trans swap?
Any help would be appreciated....
