Fitment and installation considerations

• Machining required to fit these components.
• Must use performance springs, retainers, and seals.
• Converter considerations: the stall speed should be equal to or greater than the cam’s minimum RPM in its power range; the description notes a need for a serious setup, including options like a 4000 stall converter and roller rockers for best results.

Designed for serious performance goals, this cam is a strong choice for enthusiasts who want maximum efficiency from a Ford V8 302 or 351 Cleveland combo, provided they’re prepared to pair it with the recommended supporting upgrades and proper machining.
