Has anyone ever had any problem with melting pistons? My uncle has a 1993 Lightning that has 48,000 original miles on it. He has some mods done to it including mass air conversion, headers, exhaust, racing tranny, Paxton Novi GSS Supercharger that makes about 10lbs of boost on a good day. A while back he melted the #1 piston. That piston was his fault because he forgot to turn down the timing after reinstalling the blower and it detonated. On Saturday we were going to the store and went around the corner and heard a loud whooosh sound and smelt something really bad and the truck died. Try to start it and doesn't turn over. We cut the blower belt off of it and it tries to turn over. We finally get it to barely start before it died again. It was knocking real bad. We hobbled it home (it was less than a block away) and did a compression test. No compression in the #3 cylinder this time. Has anyone had problems with destroying factory pistons in the 351?
