Quote: The same cam and head with only a cubic inch change will make aprox the same hp. The larger engine will just make it at a lower rpm.
Doesn't a stock 440 and a stock 383 HP use the same cam and heads? So if this is true then why does a stock 440 make more HP than a stock 383 HP? Now it may not make the same HP/CI but more cubes still make more power.
Years ago we used to run a bracket altered with a 383, the 383 burned up the crank so we freshened up a 440 short between meetings and changed only the short engine, left everything else alone, plus aquired a RB version of the same intake [torker 2] I think. Anyway the point being the altered picked up either 1 tenth or 1 MPH, but not both. Can't remember which one it picked up. We couldn't believe it, we were expecting a few tenths at least
