I'm just starting to put money into my Blazer now that I have another car to drive. I'm just wondering where is a good place to start performance wise. I already got new spark plugs, wires, cap and rotor, and dual catback. Where should I go from here????

Have you read many of the threads here in the 'Performance and Brainstorming' section?

Headers!

LS1 the only way to go(unless you go LS2)

Or LS7 if you've got the cash...

true that

Forget all that nonsence about the LS motors, be a man and get a 572 already, LOL.

All kidding aside, good things to look at would be an intake, maybe a power reprogrammer, headers. If you got more money maybe a cam and a performance intake manifold. Pretty much it all depends on what you want to do and how deep your wallet is.
