Ya all true but your not building no 540ci out of a real big block from the 60s! What your talking about is a full aftermarket big block. Not sure what this guy thinks, but a ls engine requires allot less work to make some seriouse street power compared to a stock 454. But really once you build a solid short block, say a 468ci with some wicked heads and a roller cam your going to have a pretty nasty engine! You can't go wrong with a stock ls3 short block making over 500hp and not worry about throwing a rod threw the motor! If I had to choose a stock short block 454 or a ls block to work with... No question I am going with an ls! Once you go into the short block it really don't matter any more.
