I thought Keith Black made pistons for a 400 maybe they are just stroker pistons???? Not sure on that. Don’t need nothing radical on compression but would like more than stock. Keep it where I can run pump gas.
Kb240 I believe, you'll probably need to deck the block .020 to get it straight & flat so they will be helpful compared to stockers, another is the low compression 440 pistons 1.928 ch.
