(Part #450811100)
                        

The Isky Max-1 is the original "3/4 race" cam grind. It is the best camshaft we have found for a majority of flathead V8-powered street rods.

  • Good low-speed power for stock carb or multi-carb intakes
  • Designed to be used with the 1949-53-style timing cover

The multi-viscosity, mineral-based COMP Cams Engine Break-In Oil Additive is fully-formulated and requires no additives or supplements. In addition, the oil is fully compatible with gasoline, methanol and high octane racing fuels.
