Re: Help identifying these pistons if possible
I believe the number Mike posted is for a LS6 piston.
Before Tonawanda went to the Gen5 engine, boring and honing big blocks rarely produced the bores they needed and they had pistons + or - for every bore size. I'm thinking this 6262975 stamped piston may be a slight size variant of the listed piston with the 6262976 part number.
How may I help you?
