What exactly are the dyno correction numbers for "NHRA HORSEPOWER RATINGS"?
In what universe does a 427 cu in small block with 13.1 compression and .630 lift with CNC heads make 430 (advertised) horsepower? I mean c'mon!
Its really like 430 HP to the wheels with 2 spark plug wires missing. LOL.

Why not, the 530hp supercharged 'LSA' made it to GM's marine line up a while back. Some ski boats and Jet boats offered it.
