    Are rubber valve cover gaskets JUNK? Pic inside

    I have used a lot of Mr. Gasket versions and like them a lot. Next up is FelPro cork composition as they are stable and firm enough to work for years. I have them on my '86 K5 stroker and they have needed very little retightening. Rubber --- er ---> generally sux. A few times I have used...

    Lost my rear end.

    It's a few days past my self-induce deadline to put this together --- and I've had two trips to Nampa Idaho and the snow and the almost Zero temps --- which sorta-kinda has put the stopper on this project until it .... 1. Stops snowing 2. Get's considerably warmer 3. I don't have to go to...

    Rear axle replacement

    "IF" being the operative here --- it doesn't always work out that they've been changed - especially when it means two gear sets. The RPO is still a good starting place. 100% of everything I've ever owned (7 K5s, 3 K1500 Sierras, 1 K40 box van, not counting a couple of Trail Blazers) have had...

    I’m interested in swapping out the TH350 for a 700R4

    Typo --- it's supposed to be a 700

    Does anyone know what an RPO code is for?

    Rear axle replacement

    The "gov-bomb' name comes from idiots spinning one wheel on ice or snow and the other tire on good traction. The little gears go crazy and ka-boom. I got over 150,000 miles on one of them hauling logs, jumping stumps and running in snow and ice hauling 3 cords of firewood up and down offroad...

    Vacuum lines where do they go

    Does it have HEI (I think so - 'cause it came out in i972-73 or so in CalEPA and CARB stats and the Feds weren't far behind. . My '86 just misses it - but I wish it had FI --- but ... no! ... and since I know your '78 doesn't have FI, you can eliminate the 4-wire connex behind the...

    Vacuum lines where do they go

    The HEI vacuum must get its signal from manifold vacuum - but it has to go through a thermostatic vacuum control valve first so it won't advance until the engine's warmed up sufficiently for the oxygen sensor(s) to start talking to the computer. On some small-displacement engines, there may be a...

    Lost my rear end.

    After many years of abuse and not being nice to my 3.08:1 Gov-Lock rear end, I blew a spider and there are no parts available in the free world of which I am aware. If I hadn't ripped some teeth off the spiders, this would have been a lot easier and cheaper. I have the loader for the Gov-Lock...

    I’m interested in swapping out the TH350 for a 700R4

    How many bands do you believe a 4700 has? Beside that --- was there ever a 700 without a LU converter? Just curious.

    Wiper Pulse Module #15598496

    Once spring happens (it's -32F here today) I will purchase a later model board with the motor and gearbox as a unit and see if it can be adapted. Don't ask why - but I may need a new column-mounted wiper control arm and associated wiring - again.

    New crate engine oil priming/ ignition timing impact if the distributor is mis-installed

    12V @1K Amps can kill, but it's usually the fields collapsing in the starter motor that generate the high Amps - much like an ignition coil that uses field-collapse to induce high voltage to the cap/rotor/plug wires and spark plugs. I've never had so much as a tingle while bumping a starter -...

    I’m interested in swapping out the TH350 for a 700R4

    I know you forgot that the 700R4 has a numerically HIGHER ratio in 1st/Low gear - compared to the 350 - right? I am and have run 3.08:1 gears in my '86 for over 30 years and have no problems --- if you want "lower" gears, there's always 4/Low. FTR: I haul an 18' 10,000 lb load of firewood...

    Wiper Pulse Module #15598496

    Has anyone tried to install the more modern self-contained wiper motor with the pulse board inside it? Will it physically fit the '87 K5?

    New crate engine oil priming/ ignition timing impact if the distributor is mis-installed

    There's a lot of discussion about the correct way to drop the distributor into the cam and the oil pump - ostensibly trying to get both of them in the right position to just fall into place. It's easier than that and there's a much smoother process that I have used professionally for over 55...

    Wiper Control Module

    Both wire/plug ends are female --- I don't see how that could work. The module is male on both ends and one end has 5 connex, the other has 7. I'm at a loss how to do that.

    EFE, traditional Heat riser & thermac informational

    I won't say it's right, the way I am running my K5 --- I removed the Thermac for stupid reasons --- but I have an Edelbrock Q-Jet and an electric choke at least and an abiding belief that a good choke is worth moving to Tecate, Mexico from Montana, Anywhere. As an aside --- I still have an...

    Wiper Control Module

    I hear you --- and kinda-sortta agree. Let me explain .... If I were to use a good working original module, it does pause at the end of one cycle and then some sort of countdown timer sends power to the wiper motor again and it goes through the same cycle over and over. What it doesn't do...

    Shuddering when braking

    I didn't notice if this vehicle in question was raised or not. If it is raised, I had this same crazy vibration when I followed the faulty instruction sheet and put the taper in, in the wrong direction. This caused a severe vibration as the rear driveshaft was being pulled out of the...

    Sbc dumping oil

    Wix is no longer Wix and the NAPA Gold WAS a Wix --- but it's kinda clouded especially if it's from Evilbay and Amazon. Confused? So am I and I just buy ACs any more. If you buy ACs, make sure they aren't counterfeit. How can you tell? Usually by the price --- but the packaging doesn't look...

    Wiper Control Module

    I don't want to resurrect a zombie post about this - but I wonder what the current thinking is about a replacement for the pulse control module under the steering column? I had one with a bad solder joint that I re-flowed and it worked for a while. Now it too, is dead and smells really bad...

    EFE, traditional Heat riser & thermac informational

    OK --- I have a little time to slay, so I have something to say about the TAC system (aka: Thermac). I worked. Very well. On some of the GM big block motorhomes and local-delivery type trucks, they used the TAC and a TVA (ne:VIDS) ignition vacuum advance/retard as the ONLY emission controls...
