Keith Black Hypereutectic Piston (flat top) for Cadillac 500 Engines, with pins.
These pistons include spiro-locks for floating pins, but can also be used with press-fit rods.
Available in .030″, .040″, and .060″ over bore sizes.
Please check for compatibility with your year / cylinder head / stroke before ordering.
This configuration is for 500 engines only, and gives you 9:1 compression with ’74-’76 120cc heads (i.e. ’74-’76 500) or 13:1 compression with ’68-’73 76cc heads (i.e. ’70-’73 500).
There are no valve reliefs included – if using these with 76cc heads, check your valve to piston clearance carefully.
These pistons are compatible with standard ring packages, but require a unique top ring gap.
Failure to follow the included instructions R.E. top ring gap often results in premature piston failure.
