How do you tell a 454 from a 502?
There are a bunch of way’s to tell what engine your looking at, one way to know is if you can see the side of the engine block (down low) You should be able to see stamped into the side of the block in big numbers, either 7.4 = 454 or 8.2 = 502. If it’s a mercruiser then this may help.
Whats the difference between a 454 and a 502?
A 502 is basically a 454 only with a larger (4.470″ I think) cylinder bore size which really starts unshrouding the valves and thus starts making some decent horsepower. The 502 requires a different block that has thicker cylinder walls to accomodate the larger bore size required to make it a 502″ engine.
