To make that much power you would most likely need a cam, long tube headers, aftermarket exhaust, cold air intake and a tune. Don`t waste your money on a throttle body spacer. It does nothing for your engine.

For the spacer, read... http://www.tahoeyukonforum.com/threads/throttle-body-spacers.954/

@JennaBear can tell you the best way to get there...

Aww well as they say ... "Fast ain't cheap and cheap ain't fast ... how fa$$$T do you want to go??? To me "gain" 350 hp means "gain" 350 hp?? So don't know what motor you have?? But say 300 hp + 350 = 650hp??

Is that what you want and can afford and add emissions compliance on top of it?? "Apparently the LS/LQ motors can do 500 hp easily enough if properly built with the right selection of parts. But your looking at $4500 dollars if your frugal and with the right combination of parts. I don't know if those motors could pass an "Emissions" test however??

You could also buy a "Crate Motor" putting out 500 hp ... don't know about emission compliance with them however??

A low boost SuperCharger or Turbo kit can net 500 hp easily but a solid base motor would be a wise idea. And those kits run $4000+. "Pro Charger" seems to claim 850 hp for there Hiboost Kit, but that can't possibly be with stock internals??

It would be wise to talk with local speed shops, machine shops and discuss with them what your goals, objective and needs are. Once you throw "Emission Compliance into the mix ... it changes everything!

Don't know about New York ... but I was a Smog Tech in Ca and in Ca ... if the motor "looked" different than the factory installed power plant ... you failed!!

Course ... I'm a car guy ... so a lot of cars got there stickers ... I had to quit that job before I got locked up.

The fastest way to bump up your horsepower is put a blower and be done with it. By the way the blower will pass emisions.

I did see the "Procharger" say CARB certified ... don't know about the High Boost 850 hp model???

And yes typically on a "stock motor" 100 to 125 hp forced induction, on these engines ... a piece of cake ... but 350 hp ... I don't know???

Well my engine is a 5.3 I just want a little more powerful I got the flow master and the cold intake already on the truck need some more power the cam I heard won't pass inspection I looking for power but I want to pass inspection as well

The towing drive has a pick up truck with stock engine told me he paid $800 for the tune to the computer and add the smaller pulley and he's getting 303 hp and his goal is to get 350 hp and he passes inspection with no problem no engine light on and his rpm go on the way down with no problems

LOL OK ... "Semantics" to me "Gain" 350 hp means well ... gain 350 hp!

I think what you "mean" is "I want at least "350" hp???" That's a whole lot simpler!! With a small block Chevy ... that's pretty much a piece of cake!

There is some value to the under drive pulleys more so on a 4 cylinder than a V8 (waste of time and money on a V8 to me but whatever.)

Your picture just shows a Vehicle with no motor??? At least that's what I see?? But if the compression and a leak down test checks out OK with your motor, your good to go!

Bolt on's and a tune can get you easily into the 350/400 hp range. CAI, Long Tube Headers (and you need Carb Certified Headers preferably) otherwise you need to have bungs welded on for 02 sensors for some headers (and without a Carb Cert that may not be legal??) Most Smog Techs just look for 02 sensors to be in place.) So whatever Headers ... "may not be a problem aslong as the 02 sensors and the Cats are there.

A free flowing Exhaust most likely a true dual exhaust. A larger throttle body and a throttle spacer (Not sure on those myself.) And a just make to sure upgrade would be a "mild cam." That and a "Tune" and your good to go.

And with the tune you need to decide if you want to run regular or premium?? With Premium ... you can run more timing advance which equates to more power. And "Black Bear" appears to be quite popular here and they can do retunes as required as you add stuff ... kinda cool I must say.

In Porsche and Toyota land ... that does not happen!

Getting to 350+ hp is a whole simpler than "gaining" 350 hp.

Should ask to talk to his mechanic.
