427 Cammer. 670HP, 7000 RPM Overhead Cam, big block in 1964. Was built to destroy Chrysler's Hemi in Nascar. Chrysler was scared of it so they threatened to pull of Nascar unless they banned the motor. the cammer then went drag racing and dominated for a few years until the Hemi motors caught up and passed it.
