"very good ones make 600 range "


I would open this question up to the whole forum, if you have a A/SA 1969 Nova with a 375 HP 396 stick and it runs 135 MPH @ 3470 in a 29.00 baro, How much HP does this take?


With 245 CFM @ 28 inches it would have to make in the 530s for HP corrected STP. My Buick flowed 213 CFM @ peak lift and made 474 HP, theres no way that BBC intake manifold is worse than the Buicks.
