Probably not the highest, but up there.

Re: Horsepower factors
Well, I just go a call from my friend that is connected to NHRA.
I will just call him "Carnac the Magnificent" Just because he is all knowing about class racing & a few other things.. He said my 73 HP example was nothing... Just look at the 1972 Chevy 454/230 in Super Stock It has a NHRA factor of 390 HP. After looking at the specs... I can see why...

Re: Horsepower factors
When I purchased my 2022 572 COPO it was rated at 430 HP. Before it made it's first NHRA run at Gainesville it was refactoring to 500 HP! It is by far the worst factored factory hot rod.
