Brian do you feel the smaller bore of the 383 hurts performance significantly over lets say a 400 or 440 block, if all things were the same ( stroke, heads,intake, cam specs) the only differnce being the larger bore of the b440 and 400?. I have always wonderd why more people don't build Stroker 383"s. Could you tel us why people seem to forget about the 383 when it comes to building big inch strokers and racing engines. What are the downfalls of it? thanks in advance. If I don't go Stroker smallblock ive always thought about building a big inch 383 but most people I talk to say forget it and go straight to the 400 or 440. Thanks in advance good sir!



i'm not brian, but the 400,has thicker main bearing webbing,& the smaller bore of the 383 shrouds the valves more than 400,440
