The Edelbrock Victor Jr. Small-Block Chevy 64cc head is a complete unit for mechanical roller cams offering serious out-of-the-box power potential—marketed for roughly 530–580 hp in competition setups. It uses angled spark plug holes, accepts standard 23° valvetrain hardware, and includes springs for mechanical roller camshafts. The 64cc chambers yield about 12.5:1 compression with a 12cc dome in a 350 V8.
