I agree 100%. But by the same token, I can put a complete aluminum top end on a 383 as well. So where are we then? Sure, you can say you can run aluminum parts on a small block and be lighter and you're right.....but what does that do to the OLD and WRONG opinion that a big block in an A body makes them nose heavy? It's just so untrue it's pathetic. Even with an all iron 440 it's untrue. The 69 factory 440 A bodies didn't handle badly at all. They had matching big block suspension components, so they were stable cars. And now someone will say something crappola stupid like, "They didn't autocross good". Well no crap. They were never built for that. It's just one stupid excuse after another to try and make the old adage "There's no substitute for cubic inches" wrong and you never will, because it ain't wrong. More cubes = more power = more weight carrying ability. No matter how you slice it, no matter what configuration you compare, the big block will win out for power every single time, as long as the builds are very similar. Bigger bores, bigger valves, bigger ports and better breathing. Yup, you can point to some 700 plus HP small blocks. But let me build a similarly equipped big block. Remember Jim Laroy? I bet there's not a small block factory iron head anywhere (excluding W2) that can flow over 700 horse power. Jim and Cody Laroy made it happen. ...and what's more, had Comp Cams not accidentally "forgotten" to turn the water on and that engine not overheated, we'd seen a big block Chrysler engine flow over 800HP through factory iron castings. A factory production small block head will never in a million years do the same thing. And before someone gets cute......NATURALLY ASPIRATED.
