The 40 440

Got about 500 miles on it ,and a trip to the track for road course, and auto cross. No clearance issue. We are changing intake, and cam but that is to get the power lower on the rpm curve for better low end torque. Better vacuum for fuel injection, and better street manners. It gas never had valve ,and piston contact. Besides valves are clear af tdc.

Yeah but , u either got the pistons down in the hole a bunch at tdc , or a very small cam --------??
still following .
