502 vs 502
I know about the older 454 / 7.4 / 502 engine family, with distributor ignition.
Even today I see that MerCruiser offer a 502.
What is that thing, from a technical standpoint?

Well, it's not a 525EFI, because they are known to dyno somewhere between 535 and 560 HP right out of the factory
Check out the new 502 520-HP *8.6L* version.

Mercury has moved away from the 496 block and now offers 3 versions of the 502 plus the new 8.6L:
8.1L Mag making 380 hp
8.1L Mag H.O. making 420 hp
And there is still the ever popular 525EFI.
Mercury Racing 520 making 520 hp (Edited, this engine is 8.6L; not 8.2L, mah bad.)
