Hi Cobalt 327,
That's for a SBC (406 CI)......... My friend have a set of Dart pro one 215cc cylinder head. We only want to know if it's prefered to put a big porting in those cylinder head...of if it's doesn't worth the money to put $$$$ in those head and buy a set of good cylinder head. We want to squize around 750 hp from this 406ci at 14.5 CR.
Me personnaly, I would go with BMF Cylinder head (18*) anyway, he need to buy piston......but if he can keep the 23* setup...and make big HP....I think we will go with it....
Yeah, if you can persuade him to step up to a better head to start with, I think
he'll be money and HP ahead at the end of the game. Or throw a bottle on it and let 'er rip!
He can get decent $$$ for the heads he has, put that towards the Brodix heads and the hit wouldn't be as bad.
