    hei distributor

    FWIW, I purchased this distributor for $83 based on the good reviews but wouldn't recommend it. https://www.amazon.com/dp/B08TB5KGNX/ The wire connections are cheap and fit rather loosely. I wish I would have bought a better one but it works for now, especially after new springs.

    Wow, went to the lightest springs and what a difference. Super peppy thru all throttle ranges now. Thanks Ricko!

    Good point on trans. It has a TH350. Don't know converter stall but I suspect it's stock.

    Ricko, not seeing this kit available anywhere - it's sold out or not available. Any other suggestions or just get a lighter spring kit? Went back and adjusted total timing to 36 degrees at 3000 rpm instead of 3800 and it's more responsive but still feels sluggish to about 1800-2000 RPM, then...

    I bought a cheap chineseium distributor just to get it running that didn't come with extra springs. What would be the best way to determine a spring vs carb issue?

    Thanks for the responses. Drove it around the pasture a little today and it hesitates when getting into throttle under load. With RPMs up, it runs great. Need to fiddle with the carb to get that dialed in but still running only headers with a 12" collector pipe. Need to get some exhaust on...

    Initially set base timing at 10 but it sounded happier at 12. Also, 36 degrees total timing was at 3800 RPM. I only checked the vacuum one time at 12/36. 10-4 on fuel filter - hasn't run in awhile and wanted to see if I was getting crap from the tank. Will change before I'm roading it.

    Just swapped in a new to me 350 in my K5. Never heard it run before today but was told it had a bigger cam in it from seller who I trust. He had no idea of the cam specs. Getting around 12 Hg at idle but the motor sounds happy with the timing set at 12 initial and 36 total. Vacuum gauge is...

    no electrical power

    Ok, I feel like an idiot now. New motor has an aluminum intake and the neg battery was grounded to the steel alternator bracket connected to that. I never checked ground with the key on but I got 11 V neg battery to engine when I did. Moved ground to the frame and it turned right over. Last...

    Good to know re: harness. That would be a last resort and one I don't want to do.

    Definitely not battery. Took a RV battery out my gate opener and same result - nothing. I'll start at the fuse panel next. All under dash wiring is a rat's nest from PO. A new Painless harness is looking nice but not for $550.

    no electrical power

    Tried the 3 suggestions above: 1. 12.0 V at fuse box with key off. Max of 1.3 V on the hot side of the fuse box with the key on. 2. Nothing happened when connecting neg post to engine ground. 3. 12.65 V at battery. 12.65 V neg battery to firewall junction block. 12.65 V neg battery to...

    no electrical power

    Update - just hooked everything back up and still no power. Have 12 V at big starter lug but will not start even when shorting across the solenoid. Also, ignore the OL on the meter above - it wasn't hooked up at the time.

    no electrical power

    Ok stumped again. I pulled the wiring harness from the starter, distr, and junction block. Tested all wires for continuity and resistance from terminal connectors back to firewall block. All were good. In the second photo, the 3 wires on the bottom were on the big solenoid stud with the...

    Ok, thanks for the replies. I'll check the fusible links this weekend.

    Should have added that I already tried a good known replacement starter that I had around.

    Finally buttoned up an engine and tranny swap in my '79 K5. Went to start it and it turned over fine, then quit working after about 30 seconds of total crank time. Now, I have no power anywhere - starter, lights, accessories. Thought it might be battery or cables but it has 12.7 Volts and...

    Oil leak

    Email them directly. They mailed me a box of everything I needed replaced at no cost. This is what they wanted.

    TH 350 bellhouse cracked and welded

    Was actually pretty easy to pull out together solo w/ a cheap HF scissor jack and moto lift. Let them down slowly, then jacked up the front end to pull out. Now do it all again with this donor and hope nothing is wrong. I'm gonna have to split them since the original NP203 has the 2wd...

    TH 350 bellhouse cracked and welded

    Finally got around to doing a 350 SBC swap on my '79 K5. Front oil pump seal is also leaking on the TH 350 and found that the bell house has been previously welded. I was going to take a stab at replacing the seal and bushing while still in the truck but now am having seconds thoughts about...

    Toyota wheels on '79 K5

    Wasn't aware they came like that - I'll check that out. Did a quick search for spacers and came up with much larger ones (1 1/2" to 2/1/2") that required using new studs. Thanks.

    Toyota wheels on '79 K5

    Recently bought some used toyota wheels w new BFG ATs (15"x31x10.5) for a steal. I had always heard you could swap 6 lug toyo wheels to squarebody chevy but not the other way around due to hub size so I bought them w/o measuring. Turns out, the front wheels rub on the tie rod ends by maybe...

    changing TH 350 oil pump seal while still in truck?

    I like this idea. I'm concerned why that seal would be leaking anyway. Thanks!

    changing TH 350 oil pump seal while still in truck?

    I'm going to do a 305 to 350 swap on my '79 Jimmy and want to fix the weeping oil pump seal behind the torque convertor while I have the motor out. Buddy of mine said don't do this unless I pull tranny and stand it up on it's tailshaft. First I've heard of this but his reasoning is that...
