Time to tear it down and replace everything. You can't just replace one piston without tearing the engine down and making sure everything else is ok. If the rest are ok, at a minimum you would need to re-balance the assembly for the new piston. My guess is that there will be more damage than what you see. On top of that, if one piston went, the others are not far behind. Sounds like a detonation problem which means that the stock pistons just can't handle the cylinder pressure due to age or material, or you may not have enough fuel in the system to keep up with the added demand of the supercharger. If you're going to run the supercharger, you need to build the engine to handle it and make sure the fuel system will be more than adequate.

what exactly happened to the piston?? Did it go due to detonation?? If so you need more fuel.

or less timing or less boost or better cooling or fix the vacuum leak or any one of about 50 different things.

To answer your question. Yes there is. Call Tyler Crocket 810 3242720. Raylar also has pistons I believe.

Figure out what made this one go before you rebuild..... Unless you like rebuilding engines all the time.

I have 7 pistons with no run time if you need one. Or just sell me your procharger kit.
