Be advised a 540 will be built on an aftermarket block. Whereas a 496 is a max bored 454 GM stock block. BIG difference from a reliability stand point. A 540 can be punched out 2 or 3 times with off the shelf pistons. You're already maxed out on a 496 and any cylinder wall damage and it's all over.... new block time.

OK, I acquiesce. I never followed or was interested in a gen 5 or 6 BBC, so I am ignorant of their potential. But let me ask of those that are up to speed; what are the percentages of 540's out there that are built on gen 5/6 factory blocks vs aftermarket (Mark IV). Be honest now.
Lastly, I apologize to Bucky for the wrong information. Although it's not a bad idea to know what block one is buying.
