'86 Jimmy 4in Lift, 40’s, tons, 8.1 Swap- 700r4 said PNNNNN

This is not a dedicated trail rig, but does trailer to the destination usually. I am currently in the planning phase of doing a 52/56" spring swap, and getting back to being more road worthy.
Overview Gallery Discussion
Ran the new wires for the starter tonight and wrapped them in thermal insulation to prevent any issues. Also pulled this little “junction box” off of the 8.1 starter. Don’t really see a reason for it.

Next on the list is getting the broken spark plug out, and throwing on plugs, wires, and manifold gaskets for final install.

Does this make the cables easier to access on the side?
I would like that to make the installation easier
 
I thought I had remembered something about gapping them to .045 when I had my 01HD 8.1 truck. AC delco is what I pulled out, I didn't know if those were factory or not.

Yes. I could look up pictures of what can happen when you skip the anti-seize, but they'd look a lot like what you just posted. :whistle: :deal:

interesting, I have never pulled a plug out that had it on there. And have never put any on a plug either...



glad to see you got it out Greg!
 
Picked up plugs, wires, manifold gaskets, and some silver high temp paint for the manifolds. Sprayed the manifolds in preparation for installing it all this weekend. Also ordered the intake bolts from the dealer which come in tomorrow. Was able to score them for $3.08 each.

What plugs would the 8.1 guys recommend for this engine? What gap should the plugs be at?

I use AC Delco Double Platinum 41-983 Spark Plugs in my 8.1Ls. GM says the gap should be .60 but you really shouldn’t gap a platinum tip plug anyway as you can damage the electrode. I screw them right into the engine fresh out of the box without even gapping them.
