Default What is difference 502EFI / 500HP?
What is the difference in a 502/415HP and a 500/470HP if both are fuel injected. I know heads, intake are different. What about cam, pistons, rods, crank, and etc?

the bare heads are the same but the Hp blue motors have better valves, screw in rocker studs and guide plates and roller rockers arms along with better valve springs along with the above already talked about

Yep, short block is the same. (except cam) or at least a couple yrs ago.

Didn't the last 500EFI's get a set of billet rods?
