I see guys say: I bored my *** motor .060and now I have these many cubes, it gotta go faster! where they miss the part about how an engine is a collection of parts and the key is how they work together and also with the car as to trans, converter, gears, etc. It ain't just about cubic inches.

Plus heads, a 408 is gonna have a hard time making a lot more power than a stock head 318 if you also slap stock 318 heads on the 408 :)

Also people seem to figure a certain hp per cid say like 1.25 hp:cid is the same difficulty no matter displacement eg.. 273/340 hp vs 408/510 hp, obviously the head flow requirement between the two is vastly different.
