What kind of minor mods should I do Such as Cam, intake, throudle body. I don't want to get out of hand and I don't think anything needs to be done to the bottom end. I just want to beef it up a little, still get decent gas milage, driver, some fun at the track. Some people have told me about an oil problem with the early LS1. how do I address that?

My 2001 vette LS1 rings allowed oil to pass through to the exhaust tips. Has to wipe them out on occasion to avoid messing the tail. It was never bad enough to cause misfire though.
GM replaced rings with redesigned units when the condition was bad enough, but not mine.
Also, my similar iron blocked 2001 Tahoe had severe piston slap, so maybe you'll hear that too.
