The 700R4 , 4L60E , will not bolt right in replacing a TH 350 Powerglide, M20, M21, trans etc you would need a different length driveshaft.

That was my understanding from way back when, was that the 700 was indeed longer than the TH350 that 2nd Gen Camaro's used, and there was no way to fit it in the drivetrain tunnel without modifying the sheetmetal of the floor. I would presume the Nova was the same. The 3rd gen Camaros came ready to fit it, and it was the only real performance transmission for the 3rd gen Camaro, as the 5spds were too light duty. My guess would be the 2nd gen Camaro used the shorter TH350 then.
