Well I have a stock 3800sc what type of performance upgrades are there for it. As of right now I've seen cold air intake, throttle body, m90 supercharger, 3.4 pullie, exhaust, superchip, and maybe port and polish the heads. Anything else post I'm trying to rebuild my engine pretty soon with some of the upgrades while I'm at school at U.T.I.

 

Have you tried reading this yet?

That pretty well covers the bulk of it- too many mods to list. If you want us to give you a specific mod list tailored to how much money you want to spend, or how much power you want to make- then tell us your budget or your goals. There are simply too many upgrades to list them all for a 3800.

Also, why are you rebuilding your engine, what is wrong with it? I hope you don't take apart the bottom end- that's a bad idea.

 

If you are driving a Monte Carlo, you don't have a series III (unless one was dropped in)

If you want to build up your Series II safely, read this thread and look under the L67 section.

 

Your biggest gains will be had with a lopey camshaft, headers, and a tune.
