200 4R is a direct replacement for the PG/TH350, no driveshaft cutting, just move the crossmember back, which I'm rather certain you need to do for the 4L60 too. The 4L is also based on the old TH400/700 r4 and has the larger case. Are people able to install that in the tri-five tunnel without cutting/modification ? I know the cast iron PG I removed from '54 was quite beefy and may have been larger than the aluminum case ones ??
My 200 is built for 450 hp 500 torque, there isn't anything that little 283 is going to do to hurt one built right.
