The number 6 piston in the GN had a meltdown at Milan dragway last week. The bore is .030 over. The piston is out and its a Repolite 21990 GM part 25531265. The piston that was pulled measures 3.830 inches in dia. It would be great if one is available for purchase. If not it looks like a complete rebuild is in order. Any ideas?
