Re: hp425 specs
I believe the engine was based off the old 420 or the 365 mag. That would have gotten you a stock GM rotating assembly. Forged crank, stock rods, rectangular port heads, forged pistons, etc. I believe that you were basically looking at the LS-6 engine with lower compression and less cam.
I take it that you meant 525 right?

I believe the same as a 420.
A 425 is a Gen V vs. 420 Gen IV.
Same as a 454mag with a much larger Crane cam and roller rockers...
