Weight reduction? LOL Any idea what happened? Detonating or lean maybe?

Looks wicked lean or a bad nitrous tune up. Ive pulled some burnt up nitrous pistons like that, usually too rich of jetting. Was it a boosted car or something?

Pretty much mistake from another shop. Car blew a forged motor a month or 2 ago. Burnt 3 pistons. They built a new shortblock but failed to see the heads had damage. The swirl bumps were burnt up next to the plug on 3 cylinders. Add too hot of a plug and it just destroys another motor.
Car runs 17 lbs of boost from a magnacharger and a 125 shot. Car has not been sprayed yet on this motor. We think the motor was hurt on the shops dyno since his first run was slower than his normal.

Yes sir. The already damaged heads caused this issue. Poor kid paid $15k for them to just do the shortblock.

You can see the aluminum melted next to the plug hole. 3 cylinders have this, same 3 that melted on his last motor.

I read the whole thing on C5.com running a ZR1plug on a boosted/nitrous setup is ridiculous. I thought my used motor going bang was bad. Its no good for both parties involved. I know you will get straight.
