For a low compression street engine what is wrong with them? What kind of pistons are they Cast, Forged, or Hypereutectic? Lot of guys don't like Hypereutectic type pistons, but for a street engine not an issue, most stock engines now have
hypereutectic style pistons, many old part number cast pistons have been replaced with hypereutectic style pistons. Just have to set a couple clearances different. Heck, I have used them with good success in mild drag engines.
next question is what kind of chamber? If it is a 906 style open chamber, I would not like them either, no quench, if using a closed chamber head then again what is wrong with them?
