Streetmaster to Airgap
Cross section, shape and then maybe flow. Maybe. My question to you is a simple one. Would you spend 5k to make a 302 head make 420 hp or 2500 to make 480 hp, because that’s the cost difference between a set of stocker heads and a set of TF heads. And the two aren’t even in the same class.
BTW, I read one of the links on gtxjohn and I didn’t see what class he was running a 318 in with 302 heads. How about letting us know exactly what Carr and class we are talking about.
