I'm impressed, I know the Bob K cammed engines run hard, but I figured they had spent so much time tuning them that they were making alot of under the curve power. 54 horsepower is quite a gain. And those flow numbers really aren't that much more than stock 906s, sometimes someone's "pocket ported heads" flow 270 cfm which I figured was the case here.

You said its a cast iron intake, I assume a cast iron six pack setup?
