    Can't make it up my driveway

    I know this problem is solved, but I wanted to add this: On older vehicles, what you think is an HEI problem can sometimes be a poor electrical connection where the HEI ignition wire feeds through the firewall connector block. Another thing might be poor connections where the feed wires from...

    Amps gauge resistor?

    It was not a true ammeter in 67-72 trucks, so I doubt it was in later trucks. Instead, the "ammeter" was really a "-/0/+" voltmeter that measured voltage drop across the known resistance of a wire running from alternator to battery.

    Help! Four Link bushings falling apart.

    If polyurethane, are they name brand like ProThane or Energy Suspension? And did you use their silicone grease? Also, the bolt goes through a metal spacer that's slightly wider than the bushings, right? Those spacers keep the bushing from being compressed.

    Fuseblock failure - What can go bad to cause it?

    On my 82's factory harness, there were two large red wires (metric but approx 11 gauge) that ran from the BAT terminal on the starter. One went to the distribution block then on to the firewall connector, but the other went straight to the firewall connector. Can't remember how the fusible...

    Stimulus Check, Header Nightmare and Regrets

    Welcome to the wonderful world of headers. It's even more fun with Vortec or aftermarket heads with raised exhaust ports! All for little to no seat-of-the-pants gains on even a mildly modified engine.

    My Rear End Build For My Low Buck Street/Race Truck

    Lowest gears I ever had were 4.56. Engine was a fairly hot 283 + .060 and trans was a Muncie M20. Even when cars were going only 60 mph on freeways, I almost always used secondary roads for even 10-15 mile trips. I will say my tires were probably only 27-28" tall. But I had a buddy with...

    Low hanging fruit to improve performance - request for input

    Good advice, but adding anything more than 12-14 degrees vacuum advance to 36 degrees "total" advance may cause pre-ignition when lightly rolling on throttle at cruising speeds. That's because these engines were set up to run very low (even negative) initial advance, so the factory tried to get...

    TBI Headers?

    Not sure what the factory would have used. If what you have in the pictures are Grade 5, that's probably fine. On another note, you may want to open up the exhaust outlets as much as you can. As I recall they are necked down to around 1-7/8" if that much. But externally, yours are nice -- no...

    TBI Headers?

    Yes, one of the worst you can buy. No comparison to Wix or Mobil 1.

    How does hood to cowl seal attach?

    Replaced the one on my 82's hood last year. Many of the clips were so hard to push in that I had to remove the hood. However, it was super easy to do with the hood on its back.

    How Fast Can A Squarebody Go?

    Haven't tried it, but even with a mild 355 (Vortec heads, Ramjet roller cam, headers, low restriction mufflers) I'd bet good money my truck would hit 100, because it's just loping along at 75 mph with probably no more than 1/3 throttle with its 2.73 axle. Mine is an 82, and either that year or...

    What’s wrong with my axle tubes?

    An axle saver bearing may have been used because bearing was rotating in the axle tube. As mentioned above, they don't cost much. Check out RockAuto. #1559 axle saver bearing/seal #6408 OE-type axle bearing

    3/4 semi floating axle to full floater swap

    Yes, slowing down helps, but it's not practical or safe to drive much slower than the traffic around you. GM didn't put 2.56 and 2.73 axles in our trucks to help them carry heavier loads, they did it for MPG ratings.

    Funny sorry about my interior

    Maybe it's there to protect the socket???

    1982 short wide bed, model specific camper $3600

    Nice looking truck from the pictures you posted. I'm surprised to see such a low price. My 82 Custom Deluxe is similar, but I replaced the 250-six and 3 speed manual with a 350 w/ auto trans. May sell it later this year and was planning to ask a lot more than that!

    GM #471634 motor mount "clam shells" for "K" trucks

    FYI, that's not rust on the parts, it's red oxide primer! Don't know why I didn't completely paint the undersides.

    GM #471634 motor mount "clam shells" for "K" trucks

    For 79-83 K10-20-30 trucks with 305-350, and 82-83 K10-20-30 trucks with 6.2 liter diesel. May fit other years, but my parts book only went up to 1983. Bead blasted and primed inside and out. Painted on the outside. I tried to use them on my 82 C10, but they aren't as tall as the 2WD...

    Cracked manifold - looking @ headers and exhaust on a budget. Suggestions?

    And that's after you jump through all kinds of hoops to make them fit! And that hi-temp paint? Plan on repainting every 1-2 years, or just living with the surface rust, especially if the truck is parked outside. Again...

    700R4 1-2 shift issue, please help!

    Before I removed the valve body, I'd watch throttle valve movement while a friend opens and closes the throttle linkage. And make sure that fast idle (choke on) is not set! Then manually move the TV lever to make sure the cable is moving the valve fully open, and that the spring is fully...

    APB - Check your cowl seam seals!

    I suggest scraping out the old seam sealer as much as possible, and then cleaning the area to be repaired with wax and grease remover (AKA Prep solve). Then lay down a wide bead of good quality seam sealer. This SEM product has worked well for me...
