Thought about the World Record 1969 RAIV 400 Trans Am Gunny this morning that runs 9.90 ET.
Just used Wallace Racing HP Calculator.
He weighs 3100 lbs seated and loaded with race fuel.
He has between 590-620 Flywheel Horsepower.
I did real Good with 592 HP Obtained No Porting !
I talked to Kern Ostrich founder of HO Racing a while back.
Told him what I built & cam specs from Isky.
He said I had 600 HP !
Kept thinking Naaaa it seems high.
MAN I WAS REAL FUCKING CLOSE 8 HP LESS !
