i have an ly6. i am going to need to flycut the pistons. instead of spending money on tools to make the cut or pay a machine shop to do it, i'm looking into getting replacement pistons for the stock 4 inch bore, stock 3.622 stroke that have l92 specific valve reliefs. shoot me some part numbers if you know of any pistons that fit the bill.

Go to Mahle's web site, I think they made a set specific for these.

I can't believe it would cost more than $100 or so to get valve reliefs cut into the pistons you already have.

my buddy said he was charged $200. if im going to spend that plus lugging the engine back and forth, or disassembling what i already put together i might as well either spend a few more dollars and get new pistons.

all i came up with from mahle was this:

doesnt look like there is anything for a stock 6.098 rod, stock bore and stock stroke.
