How much can an LS1 handle
How much can an LS1 handle How much is the bottom end worth, i was thinking like 500 to the wheels? I have 79k and was thinking of heads cam or a turbo either way should i worry about the motor because i was going to leave it stock?

With a sturdy 6-bolt main, the LS1 is actually quite stout for a small block. Its been rated by the factory to support close to 600 horsepower. GM said that during thier testing, they suffered little to no bottom end damage when designing the motor and dyno testing. Running those numbers with power adders is running on borrowed time IMO. Lower the compression and run nitrous with alot of boltons and a good cam to have the car reliable, but able to clean up at the track.
Hope this helps

theres no accurate answer to this.... at any time with a modded engine the motor can go. of course you have a better chance of the motor staying together with less mods done to the car but there is no real answer to this.. if your planning on going with high horsepower numbers than i would take the safe route and build it so you will be able to handle big numbers without a problem.
well im just not sure what to do. I want to make her a pretty fast street car. I didnt know if i should support the power first or if i could afford to. All of the posts gave me a pretty good idea of what im looking at. Im not a nitrous fan and my stall isnt set up for it. Im not really sure i even want that ne more though. Thanks guys the input is appreciated.

I have a friend who is a member here also that has a 99 ls1 with a sts kit that made 525 to the wheels. he had a little over 150,XXX miles on it when it blew. but daily drove the car making that power for about 15,000 miles and he didn't baby it at all. I think with 79k you should be fine

I know guys running 470+ and haveing no problems, a lot of it comes down to the tune and how safe you want to make it.
