Re: 79 GMC Sierra LWB 6.0L swap
It looks like an additional bracket that is spot welded on to the existing brake light switch bracket. And the pad that is on the brake pedal that the plungers contact is a bolt-on piece. Hope this helps.

Re: 79 GMC Sierra LWB 6.0L swap
Thanks Bob. Well I drove it to the exhaust shop yesterday and all the way there I was thinking that this is not the way this should run but with straight exhaust I couldn't tell what was wrong. After the exhaust was finished and I was on my way home I could tell it was a dead skip, so after a little searching I discovered a bad coil. Replaced the coil and OMG!!! this thing is a beast! OK now I am satisfied. Need to fix the tach and speedo and I will finished with this swap!!!!!!!!! Sorry still no video but I will post one.

Re: 79 GMC Sierra LWB 6.0L swap
Small update: Been a little disappointed at how my trans shifts so I took it to a trans shop today that I trust and the guy took one look at the fluid on the dip stick and said water in the fluid. After flushing 32 Qts through the trans it shifts like a new one. Also found out I have a 3.42 gear in the rear end so there is money I don't have to spend. Working on a video now! LOVE THAT 6.0 POWER!!!!!!!!!!!

Re: 79 GMC Sierra LWB 6.0L swap
Do not connect the AC through the PCM. I don't remember for sure, but somewhere around 2004 and up, the AC is controlled by a serial data signal through the PCM and the BCM (body control module) and the interior HVAC controls. I do know of one guy that tried to hook his up through the PCM and smoked it.
I have mine hooked up very simply. The green wire that ran to the original compressor..... run that to the green wire on the LS's compressor, and run the black to a ground. Done. I've been driving mine a lot running the AC, and have yet to have ANY issues with it. No problems at idle, no surging when the compressor locks up, no overheating at idle, nothing. Just hook up the green wires, ground, and go.

Re: 79 GMC Sierra LWB 6.0L swap
Thats the way I am doing mine too. I had the harness made without the A/C wiring in it just for that purpose. Cant wait for a big long smokey burnout video!!!

Re: 79 GMC Sierra LWB 6.0L swap
Hey guys, Been a while sense I posted, been watching a few of the builds. Had a problem the other day wanted to see if you guys might know what is wrong. Fuel line came off the fuel rail (the feed line) put it back on, now I have a skip. Checked the plugs installed a new set of plug wires, put a timing light on all the plug wires and all are the same "strobe" and still a skip. Have an OBDII code reader and no codes are read. Have not checked the fuel pressure so don't know if that is it. Any ideas? Thanks for the input.

Re: 79 GMC Sierra LWB 6.0L swap
Just been driving the truck. I get a lot of people asking me about the swap. They can't believe it when I raise the hood at some of the weekend drive-ins As for the injectors any way to check them?

Re: 79 GMC Sierra LWB 6.0L swap
Glad to hear you have been enjoying your truck. Not sure about checking the injectors. When you stand on it do you get the same "skip". Can you hear it at idle? I'm wondering about the compression. I know of one 2001 engine that actually had a bent valve. Of course it had a dead miss. From what your telling us, it's hard to tell if it's electical or fuel? Wish I could help more.

Re: 79 GMC Sierra LWB 6.0L swap
Check the fuel pressure. The walbro pump is a "volume" pump that your regulator controls the pressure. I would check the pressure at the fuel rail first. If all of the plugs are showing signs of a lean condition, that is exactly what direction I would start with. Also, you can pull the injectors and do a visual inspection of the spray side of the injector for trash, it may be something as simple as that.
Good Luck and keep us posted! Ed |

Re: 79 GMC Sierra LWB 6.0L swap
Well I have been pulling my hair out trying to find this skip. Took to a shop to see if they could figure it out and after about an hour it turned out to be a cracked spark plug.

Re: 79 GMC Sierra LWB 6.0L swap
Drop it buddy! Larger diameter wheels with lower profile tires, poly bushings and front and rear sway bars. Mine handles like it's on rails! I love taking an exit ramp at speeds where the Mustang in front of me is on the brakes. Lots of fun for sure.
