    4l80e and a carb

    I'm looking to remove the tbi from my 93 k2500 suburban, but I want to keep my 4l80e. I've been told that I can install a hei and carb and travel the harness installed and the 4l80e will still function normally as long as I have a rpm signal, map and tps. Does anyone know if there is any truth...

    Hey everyone I recently picked up an ex FBI 93 k2500 suburban. It had a bad motor so I replaced it. After everything was back together and running well, I started plugging everything back in that the previous owner unplugged. Everything works great except the 4wd. I can't figure out where two...

    K1500 vs K3500 difference

    I have a 95 K3500 single wheel regular cab 4x4. I know it sits alot higher than a similar setup K1500 truck. How much higher does my truck actually sit? I have 285 tires and recently added a 3" body lift to it. The cv angles are dead flat on it so its never been cranked. I just bought 2" bls for...

    Fuel pump and oil pressure gauge wont work now.

    Hey guys. I am just finishing up the carb swap on my 95 454 k3500 5 speed truck. I got everything installed and jumped in the truck to see the oil pressure gauge is pegged past 80 psi. I turned the key on and the fuel pump isnt kicking on now either. I saw on another forum that there is a wire...

    Max tire size

    So just so I make sure im correct here, If I cranked 2" and used a 2: block I would be about 2" more than you are right? I know I should be able to crank 2" easy, my cv's are dead flat right now.

    Max tire size

    Would mine rub as bad as a 1500 though? It sat much higher stock than a 1500 does. I feel like a 3" body lift and 2" suspension would be closer to 6 or 6.5" lift on a half ton correct me if im wrong. Also I am running a modified 454/5 speed over a 350/automatic so power helps alot with the...

    Max tire size

    Here is a not so good picture after the body lift and doors and fenders and stuff. As you can see it is currently on a set of nbs steel wheels. I can get whatever wheels I need. As for power, that's no big deal. I removed the tbi setup and now it's a carb'd cammed 454

    New doors and now windows wont work.

    I just came in the house from being outside messing with the truck. If I install the switches from the denali doors instead of the factory ones from my truck, the windows do work. The Switch on the passenger door does nothing though, and if I push the passenger down from the driverside it just...
