The problem is on the Dyno the fuel supply looks good. However after a few long pulls out on the street, the engine pops a ring because pressure started dropping and injector pulse went above the safe threshold, so the increased heat pinched a ring.
I am not saying the LT1 does not have tight or inconsistent ring gaps, but the engine overall in most cases can handle some power when setup correctly. Do Not Skimp on the fuel system and it will be happy. Also do not rely strictly on Dyno tuning...get the car on the street and make some high gear pulls with a Data logger.

Either way pistons are a safe drop in.
I'm gonna be likely above 650whp, so I did a full LT4 fuel system, cam fuel lobe, and pistons - So this scenario doesn't necessarily apply to me
