Hey guys, I'm just finishing up the 5.3L swap in my '86 C10. I converted the 5.3L to carb. The truck is equipped with cruise control (vacuum module), and I was wondering if anyone had figured out how to reuse the cruise control on the LS style engines? I think it's just as simple as fabbing up a bracket, but I'm curious to see if anyone else has attempted this before.
Sounds like a good swap. Pics please. Why did you go to a carby??
And welcome.

I went with a carb for several reasons, the main one being cost. The truck has dual tanks, and I didn't want to swap out the entire system for the baffled '87 tanks, 2 electric fuel pumps, and splitter valve, when everything I had already worked fine.

Very good write up on your conversion Nick. I tried to use my wrecked cars exhaust manifold, and they are the same as the GTO. Didnt fit as you also found out.
I used the original clam shell cups, and made up my own flat plates. While they work, they restrict exhaust header clearance some.
Any more updates on LS1Tech??

Thank you! I just updated it with the fuel system. I'm mostly either waiting for parts to arrive, or trying to source junkyard parts (crossmember, fan shroud, etc) at this point.
Are you going to use the 2 fuel tanks? I have 2 as well, but only one fitted at the moment. I am running an in tank pump assembly in my original tank, and am thinking I may just run a standard fuel pump to pump from the 2nd tank to the main one when needed.
Its not so easy, and cheap to get hold of parts like you blokes can, so we have to make do with what we have. I would like to eventually fit a big fuel tank behind the diff, between the chassis rails, and do away with the 2 originals.(similar to Blazer)
