LS1 Build Help. Trying to get 500HP
I have a LS1 that I purchased from a junkyard 4 years ago. It has been sitting in my garage for 4 years. Should I re-ring and bearing the block or do you think its fine?
I also plan to add a cam, and heads possibly. Does anyone know of any combos that will get me at least 500HP?
I cant decide on what cam either. Each place has a few different durations. MS3, MS4 or Thumper, Mutha Thumpr, or Big Mutha? Im getting confused on what Im looking for.
Please share your LS1 build story with end HP result or if anyone can point me in the direction of some good LS1 build articles that would be awesome. Thanks guys

You'll want to let a machine shop look at the engine and measure it to determine if it needs any work. No sense in cutting the corner and just going with it while it's sitting out. New rings and bearings aren't expensive to do if it needs it. That's of course if all it needs is a honing and a polishing on the crank.
As for combos, what is your budget? You have a number of choices in heads which is where you'll make your power. Your goal isn't difficult if you plan properly. I'd suggest browsing LS1tech.com in the dyno results section. I find it to be informative. 420-430 rwhp is basically a 500hp engine. The only other thing I can recommend is concentrate on making power where you need it and where it will do you the most good. Don't chase a number on a dyno sheet.Trey

Look up Vengeance Racing. They're a sponsor on LS1tech. They have a few head/cam/intake combos that can get you 500hp. They even have a couple that will get 500whp.
2-3k including labor won't get you very far, though.Matt
