1999 suburban performance upgrade advice

[meyeracing]

I just bought a 2wd 99 suburban, the owner before me had the trans and engine rebuilt. The engine is a 350 4 bolt main 30 over, coated hyperutectic pistons, balanced eagle crank and rods, vortec heads pocket ported with 2.02/1.60 stainless valves, double valve springs, gm performance cam, and roller lifters. The combo has 12000 miles on it, the exhaust is stock manifolds and thrush mufflers dual all the way back. I was wondering what else there is to do to these motors to squeeze more performance out of them while retaining street driving abilities. What I was thinking were some headers, any kind of programmers, fuel system upgrades, or what else any information is appreciated thank you.

Headers would be a great place to start. Have you looked at sites like www.summitracing.com or www.jegs.com . Unclear whether you still have FI or switched to carb. but those sites should cover both possibilities.

All that work and stock intake/exhaust manifolds? You still have some opportunities in both areas. If nothing else, they ought to be ported and polished.

it is FI and yes all factory intake and exhaust manifolds, yes I have looked at summit and jegs looks like there is not a whole lot to do that I have found with that factory setup for the fuel injection

 

[VanGo]

oh right, FI
Have you looked at a cold air intake? How about a performance pulley set?

I'm getting a col air intake, no I have not thought of a set of pulleys(where can I get those) I really would like to fin an aftermarket intake manifold throttle body setup but can't find one does anybody know of one that would work, I found the stealth ram intake but everybody puts them on camaros and other cars
