360 vs 383
My train of thought is what I would be presented within say....1986-1993. I had not alot of money. I had some skill and cores were plentiful and cheap. Any 360 had pistons way down in the bore ATDC. A 383 had a piston providing ideal compression. Im talking a good sound core re using as many parts as possible. A 383 rated at 320-335 hp responded so well to let's say a Mopar 474 or 484 cam. Add in headers, a Torker intake with the factory 4bbl carb or a new carb of your choice (if the core was a 2bbl 383) and the 383 ran very hard and was ALOT of fun for not a lot of $$. Also this was the gold standard for decades. A 360 with the same mods IMO would not be as powerful. The 1.88/1.60 head is a good head but the smog era compression of the 360 hurts it and was responsible for the low perf reputation the stock 360 LA has to this day. The much better compression and better head of the 383 makes it the winner. When we're talking using ONLY the blocks, and main caps of a 360 and a 383- and substituting high dollar cranks, pistons, heads and valvetrain then it's anyone's game to in.
