    Squealing turbo 400

    cheveslakr Veteran Member Senior Member Yesterday at 8:27 PM Add bookmark #1 I thought I had the solution, but failed. The turbo 400 in the K20 squeals like a wicked loose belt under acceleration, gets louder the more load it sees. It's fine around mild load. Thought it was the clearance...

    ac o-ring kit for '73

    Having an interestingly difficult time nailing down a source for a complete o-ring kit to reseal all my hoses. Right now, I'm just putting it back intact so it won't bet crud in the system. Tried Napa, tried amazon, tried the classic parts houses that sell a kit for '69-'70 chevelles.....which...

    NP 205 shifter bushing

    Been all over, internet and parts houses, no luck. This is the pop in bushing that the short linkage arm pops into on the transfer case shift bar. The Dorman part is junk, and not sure about this one pictured. Has anyone had success purchasing a replacement that actually mates to the pop-in...

    73 K20 parking brake cable routing and hardware

    Another issue in converting my C20 to a K20. I have all the cables and frame loops in great shape from the C20, and installed the C20 rear cables at the hub to the frame. Now, the routing can't be the same as the 2 wheel drive due to the t-case and the front drive shaft. So, I searched till I...

    Which Master cylinder......mismatched parts

    '73 K20, rear out of a C20 with 11 inch brakes. Hydroboost and Dana 60 out of a '89 V3500. So, the calipers are much larger capacity than a Dana 44 out of a typical K20....so that means I'd have to order the master for a K30 or V3500 to accomodate the front discs. The 1 tons never came with 11...

    Another steering shaft Jeep swap issue

    Read a few threads on this before I bought the shaft, now I've noticed the differences. This is for a '73 with tilt. It's got the splined column shaft. After getting the jeep shaft in the mail, it has a "D" upper borgeson joint. Looked at the column I stole from the '89 V3500 and it's got a "D"...

    Hydroboost power steering pump difference

    Okay, another concern on the hb conversion to my '73. Backstory, I stole all the hydroboost components off a '89 V3500, including the pump. I wanted to use my old pump, non-hb that was original to the '73, but it was missing the second port on the reservoir. I also needed the pulley, double v...

    Carpet for K20 bastard

    I've got a '73 C20, converting to K20 and using the tranny hump from a 89 V2500. Do I buy the carpet for the year appropriate? LMC doesn't even cover the v3500, so if I buy for the year, do I pick the '80-87 version of their carpet?

    89 454 exhaust manifolds BIG

    Pulled these off the 89 V3500 and set them aside. Then, today, I pulled the original manifolds off my '73 C20 454 and the difference in size is very noticeable, not the outlet, but the runners themselves and the log. My question is, has anyone flow tested these to give numbers to what I suspect...

    Body weights, for mockup

    I've got to measure for my drivelines and only have a rolling chassis, no body. I could guestimate bed, loaded cab, front clip with rad, engine components, fluids etc.....but I'm sure some have been through this already and share their research. I've got the naked block, trans and transfer...

    Transmission x-member 4X confusion

    I may have overthought this.....I'm converting my '73 C20 to a K20 using the drivetrain from a '89 Dually 1 ton 3+3. Using the 454, turbo 400 and the 205. The X-member I'm also using from the dually, but the frame measures 8 inches deep, while the frame I'm using is 6 inches deep. The added 2...

    1989 K30 or K3500 Dana 60

    I'm going through the D60 front from a '89 1 ton dually....putting in a '76 K20 frame, and all this to convert my '73 C20 to four wheel drive. Okay......the D60 is in need of all new brakes, bearings, seals and a good clean up. Went to Napa today and they looked up a 89 K30....no such thing...

    When to replace kingpins?

    I just tore down the '89 K30 Dana 60 and found the upper kingpins to be slightly tarnished, or a bit of very light pitting on both sides, the area facing the center of the truck. Never driven this, it's from a parts rig. I can run my finger across the pass. side and it's undetectable, the other...

    82 3+3 dually goodies

    I've inherited a '82 3+3 dually that's got the 454, dana 60 front, auto, 205, and I believe 4.10 gears......but not sure of that. It's just rusty enough to not be a good candidate to put back on the road. Now.....I've got a '73 C20 Cheyenne Super 454 that I've wanted to change over to a 4x4...
