Piston ID Help
Bought a complete L98, Alum. head motor out of a 1989 Corvette. Pistons are dished with four (4) valve reliefs in the top. Factory number on the inside of the skirt is 10128213. Anyone know what they are or at least what compression ratio they are supposed to be. Number does not come up at nasty.com...thanks!!

Re: Piston ID Help
Thanks so much for the info. I just wasn't sure as I have read 9:1 as well. Wonder why that piston number doesn't come up anywhere. Rebuilding the motor...any advise on a replacement piston. Thanks again!
