383 vs 360 in an A 68 Cuda
Love the logic on this site if someone wants to build something smaller than a 360 no replacement for displacement 360 is the way to go, if bigger than 360 no reason for big block 360 can be built to similar level, and if you need big size dump a bunch of money into a 360 to make it the same size a 400 is stock and a 383 can get close to with an overbore and 440 eclipse. Cause we all know how smaller bore breath better than larger ones :).
Big blocks stronger and more power potential.
