My forged pistons were kinda custom - - their not available from Speed-Pro as a production part - - at least not yet. The compression distance was 1.350 - - plenty of room for the ring pack. I went to a 1/16-1/16-4.0mm ring set to gather a bit more room. The
oil ring assembly is from a standard bore late model 460 Ford. Lots of skirt so piston slap is a non-issue.
Interesting news on the distributor.
