Ask blown06 he gutted his harness or Nelson, I know he's done a lot of wiring stuff. Nonnieselman does a lot of harness work too.

 

didnt blown06 have alot of bcm issues after gutting his harness?

 

I don't plan to touch the bcm harness itself. We're just gonna pull PCM and its harness and go from there. We'll figure something out. If we can't get the A/C to work, no big deal. I usually just drive it on the weekends at night anyways

 

a/c delete?

 

If that's what it comes to, that's I'll do. I really wanted to keep it but lord knows this thing can use all the help it can get shedding weight lol. I think I can get it down between 3900-4000 with me in it with the ac still there

 

start cutting theres all kinds of crap under the truck that isnt necessary.

 

That's the plan. Fuel cell, cut out the crossbars that don't need to be there, cuts the ones out that do need to be there and replace with chromoly or mild steel, gonna put some kirkeys with covers inside(because I've always wanted them), changing to 5 lug with some lighter wheels(that's going to save 100+ # and in rotating weight)

Really wanted to keep that ac though lol

 

I've gotta couple ideas on the a/c. Only thing I don't know about is the pressure switches/sensors..

 

Hi I'm Steve and I have a 2006 GMC Sierra that I took the 4.3 out a replaced it with a 410 stroked LS Carbed. Originally had a quick fuel and even tho I'm sure their a quallity carb the one I had sucked eggs. Ran really rich and changing jets,power valves and doing all the proper adjustments could not get it to lean out. It cost me my first engine. Now I have a 6.0 built by LME in Houston,Tx. It has a Pro Systems 850 on it good for 600 horse. Have ended up taking it off the street as it was my daily driver. All I did for carb linkage was the Lokar and it hooked right to my pedal and to the carb. Just had to shorten it a bit. Not using any of the PCM. Using only the MSD 6LS it is real easy to program timimg and all.
I have removed sway bar all interior and replaced the seat with a jegs race seat. Have a roll bar and a lexan back window. All guages are Autometer. Radio was removed to make a spot for switches. Have a Aeromotive fuel pump A1000. and 3 regulators 1 to carb 1 to fuel side of nos and 1 for return. The stock fuel pump in tank is to much pressure for carb and I was told that there wasn't a regulator that could go from 65 70 lbs down to 7 lbs. So i opted to go this route. I know there probably some one out there that has a different way to go. This is the way I chose.
I have a TCI turbo 350 trans. Have a Edelbrock progressive controller for the Nos and haven't been able to use it in full yet. My limited slip rearend isn't enough to get both sides hooking up. Ran 11.80's @113 on motor. After we install spool and readjust Cal-Tracs that should help. Am looking at 11.50's on motor, who knows where a 100 shot will take me. Am planning on 250 Max
I'm sure your build will really be a lot of fun and fast. I din't do the wiring as I'm not good at that.A friend did it. I know the whole harness off the computer is cut. Good luck. Carbs are good on a LS and I'll put mine up against EFI any time.

 

Thanks for the reply Steve. I've got many of my ideas from looking at your truck. I think I've sent you a couple messages about it actually. We love your truck down here!

Take a look at my build thread and you'll see some ideas of yours I've stolen lol
