I came across these while going through a 1970 Ford publication in the Mild to Wild series. I thought there might be some interest in the cam specs, and that Ford got to nearly 350 HP, 328 Ft Lbs torque out of a 289 using over the counter Ford parts. Carburetor was a 600 cfm Holly on a C9OZ 9424-D Al. manifold and the heads were 351W.
