Well,
I think the power adder engines are a different thread dont you?.
The real point is the guy is out racing and mixin it up instead of home dead in the garage because its the combo he grew up with and loves it. It may not be the fastest combo but its rated 415hp!!! That's alot of hp's for an inline valve motor wt a 208 intake valve.
Hat's off to bischoff for getn r done!!!
PS the replacement head flowed way better bout 320cfm intakes at 600" see pics on lynn's photo gallery
Now only if we can get the car out west so his brother will put his foot in it!!!!!
