Reply to "what to do"

David THANKS, you kind of answered my question, but you raised another one.

The BT heads have "Yates" ports. The Yates exhaust port is rather square, I've always thought a 4V exhaust header might bolt right up, apparently so. You probably have the "low" exhaust port, the higher port would probably have created interference between the chassis & exhaust system.

The question you raise is that you tested the motor with a dual plane intake. Have any idea which dual plane intake & what was done to make it fit? I was not aware any dual plane Cleveland intake could be made to fit a pair of Yates type heads on a C block.

I hope I don't come across as a critical SOB! All joking aside, your motor epitomizes what I preach here on the DTBB. Stroker crank, hydraulic roller cam, modern alloy heads, 500 ft/lbs of torque, all in a drivable & reliable package, nothing radical, with a powerband around 2000 to 6000 rpm. It happens to look bitchen too! Your motor is the George Pence Poster Motor!

your friend on the DTBB, George
