All Chevys used the same diameter flywheel?
All Chevys used the same starters?
Funny, I have had person experiances with all these, and more. Like:
Some chevy blocks are missing motor mount bolt holes, starter mounting holes,threaded holes in the ends of the cylinder heads for bolting up incidentals, like alternators, no oil filter vs canister oil filter, vs spin on oil filter, 3 different valve cover bolt patterns, no threaded hole for securing the crank damper,long vs short water pumps, left and right side dipsticks, 2 piece and 1 piece rear main seals, different thickness front oil pan seals, etc. Just like the Fords, it seems that Chevy made a few running changes during its lifespan. As for how much easier it would have been to convert a 66 283 Chevy Nova from auto to 4 speed, hope that you have one of the special Chevy II only blocks and bellhousings to make use of the factory clutch linkage fit properly!
Seems that doing your homework when it comes to mixing and matching engine and car parts is a good idea, whether you are working on a Ford OR a Chevy!:D
