The LT1 engine is high compression so a supercharger is risking it. Most guys that break are the piston ringlands that let go. If you drive like a sane person, you can get away with a 4.5 lb supercharger for a while. But, you'll like the added power and want to increase boost which will end up hurting your engine. So, you either go with a 4.5 lb supercharger and enjoy it, or start by rebuilding your engine with forged blower pistons with lower compression in preparation for a 6-15 lb blower. I've been driving my 93 for 3-1/2 years with my Powerdyne 4.5 and no problems so far. But, I don't race it or abuse it.
