I think the advantage of the CHI heads is that the port velocity is so high. Sure, anyone can make 600hp with 340ci and a big cam, but making that much power and having the torque to back it up is a different scenario.

CHI has several dyno charts and magazine articles showing 408's Clevelands and Clevors that make 650hp up top, and are still making 500 lb-ft at 2500 rpm. The 3V port is an awesome middle ground.

I think that's the reason why CHI is the choice for all the Engine Masters Competitions....a broad torque curve is what it takes to win there, and that's what it takes to get a thrill in a street car.
