    Brainstorming about my 81 GMC

    If it has nuts or bolts, or wires, I’ll mess with it. While I can and have done a little bodywork, it’s definitely not my area of expertise. Which means paying someone to do a job that I would t be satisfied with if I attempted it myself! All that fabrication and tweaking no doubt would take...

    Brainstorming about my 81 GMC

    I was aware of the cowl/hood issues, didn’t know about the hood hinges. I think I’ll do the suburban front end, I prefer that look. My dad always had a beater squarebody. He bought his first when the trucks got old enough to become beaters. Since they were beaters and work trucks, I had lots of...

    Carb recommendation 1974 Cheyenne 454CI

    Q-Jet! Either rebuild the factory carb CORRECTLY (including the worn out throttle shaft bores) or get one done by a specialist.

    Electrical Load Causing Weak Blower Motor?

    Find someone with a clamp on ammeter. With the engine idling at an elevated speed, turn on every electrical accessory, put the clamp on the positive battery cables, and take a reading. If that number exceeds your alternator output, it’s time to upgrade. If you think the problem is in the...

    Brainstorming about my 81 GMC

    I’m slowly gathering parts for when my 81 GMC goes in for major renovation. I’m hoping life calms down enough that I can actually get started soon. I have always preferred the older model round headlights. After some discussion here, I quickly realized that’s entirely too much hassle to...

    Transmission swap questions

    Bingo! If it ain’t broke, don’t fix it. While technically the trans is “broke” unless you really plan to beat up on the truck, there is no need to “fix it” with a different trans. As mentioned, there are several different families of the 4l60. The earlier 82-86 aren’t as desirable, the...

    Trying to sort a rats nest.

    Cruise the vacuum hose goes to the cruise servo. It’s a backup, if you hit the brakes and the cruise doesn’t electrically disengage, the vaccum switches dumps the vacuum and the servo releases the throttle. That connector is where the pink/purple wire plugs in.

    Any GM 2.2 engine experts in readerland?

    Great big steaming piles of horse excrement!! After a few questions and some research, it appears the big difference is the tone wheel and crank sensors are completely different. There are other design changes, but that’s the big headache. I have little doubt the problem could be overcome, but...

    Any GM 2.2 engine experts in readerland?

    Correction: the engine, rearend, FACTORY wheels with decent tires is worth the 400 bucks. Especially once I send what’s left to that big scrapyard in the sky. The 97 has some hideous aftermarket chrome wheels on it now. Not sure what brand they are. I’m sure whoever bought them originally was...

    Any GM 2.2 engine experts in readerland?

    Last year my son bought a 97 S-10 with the rompin stompin 2.2 engine and a 5 speed. A couple weeks ago, the engine started making some VERY bad sounds, it locked up tight on the drive home. Over the weekend, I found what is quite possibly the most rusted out 99 S10, also a 2.2 but with an...

    Cruise control DBW PSI harness

    What wires/signals does your EFI need to function? Pretty sure there is a cruise diagnostic chart somewhere in the electrical forum.

    Cruise Control Wiring

    The VSS signal comes off the speedo head, and plugs into the speed buffer. It’s a greenish colored box somewhere near the speedometer housing. There is a connector that comes out of that for the speed sensor signal the the ecm and cruise module. There is an also a yellowish colored module that...

    How to remove the fuse box from the bulkhead connector

    The 5/16 bolt under the hood holds the engine compartment half of the harness to the dash harness/fuse box. More than likely , you will need a heat gun to soften the sealer/glue that GM used to weatherproof the terminals. The 2 long screw under the dash hold the fuse box/firewall connector to...
