Gen6 Cranks
I had always thought that the Gen6 454 and 502 shared the same crank and rods, (and heads, cam, lifters etc.) but the pistons were obviously different.
When I look at forged cranks in AM catalogs, I see 454 listed with 502. But when I look at GM numbers in, say, the GM crate motors (HO's), and at BAM, for marine motors, I see different part numbers for 454 and 502 forged cranks.
The 502/450 and 502/415 are the same, as is the ZZ502 cranks.
Can anybody tell me what is the difference in Gen6 OE forged 454 and 502 BBC cranks?
What am I not seeing, that is a different feature, between the two?
