'71 Jimmy - "Black Taco" - Bit of an Update (4/5/11)

Well, got the email from my dad today that the brakes are functional, so he is pulling the Jimmy home sometime this weekend.

This thread is basically a placeholder until I get home for the holidays, since I'm at college in Austin, and won't really be able to get anything done until then.

Here's some before pictures from when we picked it up:

























Specs:
1971 GMC Jimmy
GM "TargetMaster" 4 bolt 350 Crate
SM465
NP205
Dana44F(factory lockouts)/GM12bR

No A/C, Manual Steering, does have power brakes. All the trim/light lenses/glass are good except for the passenger side vent window.

Has an 8track AM/FM radio and a CB (antenna is still on the truck)

Engine looks to be in good shape even after sitting for this long, turns freely and the oil actually still looks alright. Will need a good going over and full tune up.

However, the big kicker is that the electrical system isn't working. A hot battery doesn't give power to anything operated by the key, so I will have to once again pull out the multimeter and start checking what has voltage and what doesn't. oh joy.

I'm stoked and can't wait to get back in town and start wrenching...i miss it haha

Looks like a great starting point, even with the electrical issues. Although not exactly cheap, you might want to consider going with new engine bay harnesses. They tend to be pretty brittle and lead to all types of problems. I replaced mine in my K5. The under dash harness was left as it was.

I did a complete rewire on my '73 with an EZWiring harness, so if it looks like I can't just repair the existing setup, I'll consider replacing some stuff. Thanks!

grooooan. Just plan on buying a completely new wiring harness from EZ Wiring or Painless and re-wiring the whole thing. Any wiring that may still be useable is bound to be giving up the ghost soon.

Those old Target 350's put out around 250HP/280lb-ft I believe. Looks like it has a Holley intake and headers so it should be plenty peppy. I recommend using remflex header gaskets it the ones that are on it start to leak. I like the upper radiator hose hackery lol

The Olive green color has got to be THE cleanest color on these things. I saw a 1st-gen picture on this site of one with the same color scheme on 39.5" Iroks that was just stunning.

mmmm....that's nice. think the "medium olive" listed on the build sheet has less blue than that truck. either way it'll look sweet.

right, that one has a blue mixed in and the 'medium' olive looks great also.

Really, you could paint a 1st-gen blazer pink or neon green and it'll still look great

yes we still want to keep it as near to stock as we can. I will be home in 2 weeks, and I want to spend at least a couple of hours that weekend cleaning it up and "taking inventory" if nothing else.
