Pretty sure any nova from 1968 to 1976. some had 8.5's, most had 8.2's.

My 8.5 came out of a 74 350 nova.

1 inch narrower didn't make a noticeable difference for me, but I run a narrow 215/70/14.

it's true if you install an 8.5 out of a Nova you will have to shorten your driveline an inch (more like 1 1/2 inches, you'll have to measure it) and replace the back u-joint. I did the swap last year.
