Really. I thought it took something in the 350cfm/325cc range to get there with 500ci on pump gas? I havent keep up on the trick flow posts. How are the trick flow heads better than victors or indy 440-1 and ez?
My pump gas 470 is making 685 hp with out of the box Trick Flow heads. So that easily meets your 650 to 700 goal. Now the 685 is with dyno headers and a low restriction dyno muffler so you'll take a bit of a hit in a car. On the flip side, I'm pretty sure I'll be at or above 700 hp once I install the ported intake manifold.
