what do i need for boost? i got a 99 s10 with a 4.3 in it for now but im gonna swap an ls1 in it soon. i was decided on a built ls1 but after seeing the dyno on the sts kit ichanged my mind. what all do i need to do to the engine to stand up to around 500 hp or so? thanks
fuel(injectors, pump etc), almost perfect tuning(keeping it on the rich side of course) and some praying to god that it holds lol...thats if u dont want to spend big money, but to be really safe swap pistons for forged ones with nice quality rings, decent heads/cam if u want to wake it up alil more, thats basically it more or less...should be easily over 500 with that with 'some' piece of mind 
hope this helps

haha well said. i saw this one place selling a complete ls1 with forged internals for like 3k so im gonna probly go that route. any kind of cam/head package you can recommend for boosting? it should be able to make 450-475 on stock parts right?

5.7L aluminum or 6.0L iron LS1 block, fully machined, deck squared, torque plate honed, line honed mains, ARP main studs, stock reground crankshaft race prepped, 4340 H-beam rods, forged flat top pistons, Plasma moly rings, Clevite bearings, Fully balanced, blueprinted, and assembled.
thats the description for it.

A stock LS1 bottom end will generally handle 500 rwhp, above 500 rwhp and you're taking a gamble. It is all about keeping detonation away, meaning you have to have a good tune, fuel pressure and injectors. I have heard of too many forced induction guys thinking they can wait on getting a tune, and end up ruining their #7 piston, sometimes the block and heads as well. Bob
