Spoke with JE Pistons.. the pistons I have are old as they have no engraving on them.. and also, JE would like to see a max clearance of .0045..
So it looks like I will be shopping for new pistons..
Thanks to everyone for their assistance
Don, that is a bunch of baloney sauce JE, Arias,Forged True and most of the other Hi Po piston makers made there original forged race pistons in the loose alloy aluminum, hence they wanted .007+ piston to wall clearances. It was in the last ten to twenty years that the pistons companys started offering the tight alloy forged aluminum pistons for custom engine builders for street use, .0040+ clearances. It sounds like the person you contacted at JE wanted to make a sell, they do work on commision Go to JE web site and see if they have in thier tech section the way to tell which alloy your pistons are I think Ross tells you to look at the bottom edge of the oil ring groove, if it is cut with a 45 degree angle it is one alloy, if it isn't cut it is the other alloy JE was sold several years ago by the Calvert brothers, not John Calvert of Cal Tracs, I think The Calvert Bros. started CP Pisons after the non compete clause expired with the purchasers of JE Pistons. I think they sold CP pistons recently also or maybe they bought Carillo rods and merged the two comanys together There has to be a way to tell Let us know what you do and find out
