    Oil Filters with good anti-drainback valves?

    Hello everyone! I'm looking for an oil filter which has an anti-drainback valve which doesn't fail after a month or so. This would be for the K1500 in my signature. I've used filters from AC Delco, Purolator (Red one), Bosch(?) and WIX. They all last about two weeks before they fail, leaving...

    How to troubleshoot erratic tachometer? (TBI)

    Hello everyone, Truck is a 1989 K1500, factory five speed 350 TBI but with the moonies to needles swap. I ran an auxiliary wire from the coil to drive the tach within the cluster I pulled from a treasure yard some four years ago. Story time/background: For about the past year and a half the...

    GM TopKick Instrument Cluster?

    It never dawned on me until a few days ago but GM Top Kick trucks have the '88-'94 dash but also a tach. Guess even in 1988 they had a tach as well. Also noteworthy is the climate control panel which is black, perhaps those also run off the old 8v signal? If it does, it would allow us earlier...

    Please check these RPO's - Does this donor truck have a 14 bolt SF?

    I'm looking to buy a parts truck from a guy at work He originally said it was a '94 454 Suburban with 4x4. I'm interested in doing the 14 bolt SF swap and perhaps taking a few other parts from the truck, and I figured his truck might just have what I'm looking for. Anyway, he finally sent me...

    Bumper Interchangeability???

    Hey everyone! About two weeks ago Ashley and I acquired a replacement truck for her '92 F150- a '92 C1500, regular cab long box, 350 with a five speed. It had a smashed front bumper so I went to a yard and got the best one I could find to replace it. Donor vehicle was a 1996(?) Suburban I...

    '88-'94 Rear Defogger Swap

    Fellas! I've got a '89 K1500 regular cab that I'd like to swap rear defrost onto. Truck currently has the dumb two piece slider window and of course the tab to keep them closed is busted. I would rather have a single piece window and the idea of defrost is groovy but I've only seen it on '95+...

    10 to 14 bolt SF swap - Quick Questions

    Hey all! Backstory/rambling: I've got an '89 K1500, RC/SB 350, 5 speed with 3.73's. Truck currently has about 235k miles. I might end up towing a car trailer occasionally and hear nothing but bad things about the 10 bolt.. I think the rear end is original and it's been flawless in the 10k...

    Factory Steelies & Hubcap Question

    Hey all! So I love the look of the factory steel wheels, when painted as the factory intended, some sort of argent gray with the factory hub caps & bright trim rings. My question is, were these ever available for 4x4 halfton trucks? I've never seen them before aside from the steel wheel spare...

    HVAC control head swap, "Max A/C" Style - Wiring Diagram Needed.

    Hey everyone. Recently I swapped the factory HVAC head in my '89 for one from a '93 or '94 truck to gain the "Max A/C" button. Things were fine for a few days but now I'm having problems like everyone else does with the swap. Long story short, I was wondering if anyone has the diagram for the...

    Electric Blend door stuck?

    Hey all! Truck is an '89 with electric controls.. Before the temps dipped into single digits I had perfect heat. However, I go to drive the truck this morning and while it's at temperature, the only thing coming from the vents is frosty air. I tried running the heat to cold, then to hot again...

    Erratic Idle - Possible Symptoms & Fix (350 TBI)

    Hey all, Thought I'd share this with you guys since I don't think I've seen anyone mention this before, I've heard about the throttle shaft & gaskets being blown out but not this.. Also more fuel for the fire that says, "Diagnose, not replace." Anyway, I've had an erratic idle problem with...

    Growling noise in 4x4 - axle or wheel bearing?

    Hi fellas, Well, it's that time of year where 4x4 is handy and since I started using mine I noticed there is a growling noise coming from the front left of the truck whenever it is in 4x4 hi, starting around 20 mph. I don't hear it any other time and the noise isn't always there, sometimes it...

    Trip Odometer quit - Will later years work?

    Hey everyone! Before I go scouring yards for a replacement trip odometer, will they even work? Our truck has the unicorn '91 cluster with tach that I swapped in place of the old slice-o-pie junk. I've already determined that the odometer for the S-o-P clusters won't work but I'm not sure...

    Looking to add power windows & locks to my '89. Is it do-able?

    Hey everyone, We recently resurrected our '89 K1500 by putting a "new" used motor in it. Runs great and stuff so now it might become my DD. I'd like to add power windows & locks to it but would like to know if it's a straight forward swap or if the dash has to come out to accommodate a new...

    Vortec vs TBI - Stupid Questions, need answers please :)

    Hey everyone, how are you and your trucks doing? Ours isn't so great. Some may remember that we bought an '89 K1500 regular cab, shortbox with a 350 and a five speed, that Getrag nastiness. Anyway, the original engine has 225k miles and the previous owner burnt up a valve and it runs like...

    Rough Idle - Chevy 350 TBI

    Hey everyone, We bought an '89 Chevy K1500 with a 350 in it and 224k miles, with the nasty Getrag trans I knew nothing about until after purchasing the truck. Anyway, we have been chasing a rough idle ever since we got it. Well, it didn't seem to idle rough until a few weeks after we bought...

    Transmission Knocking Noise? (Getrag 5LM60)

    Hey everyone, long time no chat! We begrudgingly sold/traded our C3500 for some cash and an old Ferd F250... It wasn't long until we got our next project though, a 1989 Chevy K1500. I'll see about getting some pictures uploaded soon. Anyway here's the issue: When the trans fluid...

    Which lube works best with a SM465?

    I'm currently running what the owner's manual suggested, gear lube of mumble-mumble viscosity. But, the thing shifts like a turd. I was wondering if people have used the special lube required for NV4500's in an SM for improved shift quality. What about ATF? Heard one guy used motor oil but...

    WTB: 2wd Reg cab, long box GMT400 with NV4500 trans.

    Doesn't have to run and can be in horrible shape. I really only need the trans, driveshaft and the hardware to make it work in our '88 C3500. Guess I'd prefer 92-95 as those had the external slave cylinder but wouldn't mind the later versions either. Beggars can't be choosers, right?

    C3500 - SM465 to NV4500 swap questions..

    Good morning. I'm sure this has been beaten to death but I can't exactly find the information I need... Looking to swap our clunky SM465 for a NV4500. Heard that the 92-95 transmissions have RPO code MT8 and would be a direct swap. GM bellhousing to engine is the same regardless of V8 small...
