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.
