[Anyone got advice on some cheap power adders or mods for a 1994 gmc yukon sle with the stock 5.7l tbi V8]

I mean changing out your ring and pinion gears, and also going limited slip or locker while you're at it. The 4.10s would make a HUGE difference in how the truck launched. As far as the tranny goes, there is a first gear servo that can be switched out for one from a Corvette. It makes first gear one mean bitch. Rear end gears PLUS the servo upgrade will make the truck feel like a completely different ride.

ok cool i will definitley be looking for that servo and rear end, gears might have to wait becuase of my budget but thanks for all the help and is there anything i can do with the stock throttle body to improve performance

throttle body spacers are a good addition with an exhaust and cold air intake

thats how my 4.3 tbi is set up

How much of a difference did the spacer and cold air intake make when you installed it? Any noticable changes?

the thing that was most noticeable was the throttle responce also like above are good upgrades as well

also have you checked out the http://www.fullsizec...on/performance/

Best thing for that motor is ditching that throttle body setup, its a turd from the factory. Upgrading to a unti from someone like Edelbrock helps a bunch. I had a pre-Vortec in my 1990 regular cab with the 350. I had throttle body spacer, K&N, and 3 inch exhaust all the way back. I also did a Hypertech chip. Easiest way to make the truck FEEL faster is to swap out gears to something LOW and to also put a Corvette servo for 1st gear. A nice B&M shift kit goes a long way too. Long tubes are cheap for the truck as well. Get it to breathe, get it some fuel, and get it geared to jump out of the hole. If gas isn't an issue, I'd recommend 3.73s or 4.10s(like the 454SS came with)

Now when you say swap out gears are you referring to swapping the tranny or changing up the gears currently in it and i've been contemplating on whether to get 3.73 or 4.10 but not really sure which would be better as far as quicker take offs are concerned.

Looking to gain some power from my old 350 seeing as it is basically stock except for the plug wires. Also this is not a vortec.

thanks everyone for the help we sanded it down and it is fine now

[How do i stop the buzzing noise coming from my door speakers]

I'll sand down the painted surfaces on or around the bolt to see if it works. If that doesnt work then ill move it.

[How do i stop the buzzing noise coming from my door speakers]

sure is. Where is your ground at?

My Friend says that it is grounded to a bolt connected to the rear seat

Move it. That's not really a good spot. Did they sand all the paint off the metal?

No there is still paint there

[How do i stop the buzzing noise coming from my door speakers]

bad ground?

sounds like a familiar problem, i just don't remember what exactly causes it..

I was thinking the same thing but im not 100%

[How do i stop the buzzing noise coming from my door speakers]

Is it from the alt? When you rev up the engine does the buzz change?

yes it does change as the engine revs so it is the alternator then?

Ok so i have been helping a friend put in his system in his 98 silverado and i have everything ran correctly (rca's away from power and ground cables etc..) and there is still this buzzing or humming noise through the speakers it doesnt affect the music because when you turn up the volume it isnt noticable but when there is nothing playing you can hear it. He is running 4 alpine type r components and the amp powering them a is a quart 4x125. I was thinking it could be a ground loop but im not positive.
