    NV4500 years?

    About 15 years ago I install a NV4500 from an unknown year. I had the transmission rebuild, the NP205 rebuilt, used the engine bell housing from advance adaptors, and the NV4500 to NP205 round adaptor from Advance Adaptor, external hydo clutch linkage, Ebay, used clutch peddle assy. It was all...

    Auto to manual advice

    I have a fairly still low mileage GM crate motor that once had the non lock up tb350 auto. With mud tires the wheels would spin just hitting the gas at 20 mph. Everything was good except the rpms where way to high at highway speeds and MPG was lucky to hit 10s. I replaced the auto with an...

    Looking for no bs, tested, quality vacuum caps..

    Nothing has worked better for me over the last 40 years then a very short piece of fuel hose plugged with a screw or bolt.

    Testing the horn circuit

    I had the same problem years ago the day I need to inspect my truck. Took the steering wheel apart and notice it was missing a ground. Do not know where the ground is located so I added a new one from the steering column mount bracket to the frame of the dash. Also solve the blinker not...

    Power Steering

    I have own Square body pickups and Suburbans since they were new. Most have had this problem. It is most noticeable if you back up a lot of trailers. A new V belt and proper tension would fix it for a while. However it did not take long before the noise would come back. Even without the...

    79 K20 NBS Master Cylinder Swap

    I have a 79 K truck 4x4 with a 82 C10 cab. The title says 3/4 ton but it is 6 lug. Front disk rear drums. Being I did the cab swap twenty years ago I can not recall what master cylinder I used. The brakes have never been great but most likely the norm in the 70s. I recently read of NBS...

    Anybody ever installed a newer transmission on an older engine.

    I swapped out a turbo 350 with a NV4500 about 10 years ago. I do not know if in 1979 K15 automatic trucks rear ends had a higher ratio than an automatic. Was very pleased with the swap getting another 4 or 5 MPG but the rear end ratio is too high to use 5th gear.

    Mechanical or Electric Fuel Pump.... Thoughts?

    I installed both and here is why. If your truck is not a daily driver the new ETHANOL GAS will not be in the fuel bowl when your try to start it. I run the electric fuel pump to fill the bowl for about 30 seconds before I start cranking the engine. Now that they have the NON-ETHANOL GAS right...

    NV4500 Swap - Clutch/Hydraulics Dilemma

    I do not know if it is just me but the 5 speed in my 95 F150 with a straight six seem to have a better over all gear ratio between gears than the NV4500. I am only running BFG 33 " I need to have my local drive line shop drive it to see if they would recommend a rear end gear ratio change...

    NV4500 Swap - Clutch/Hydraulics Dilemma

    I did the swap about 10 years ago. I started out with a 79 k20 GMC with a new GM crate engine and a turbo350 without a lock up convertor. AA bell housing, external hydro clutch, with an after market clutch pedal that was tricky to line up the linkage. It also had a remote under the hood hydro...

    Help! Horn not working.

    My 82 truck horn worked fine for just about 40 years and just stopped on the morning it needed to be inspected. I took the steering wheel grounding ring and sanded and wire brushed off all of the rust. Put it back together and no beep beep. Noticed that if I took a wire to the dash screw to...

    10l80 10 speed transmission into square body suburban.

    You are my new hero. I have been wondering if the MPG gains are more of a factor of a transmission with more gears that just a new type engine. Thanks in advance for charting new waters.

    I have a 1978 GMC 3/4 ton 4x4 32" BFG mud terrain, Pace 350 crate engine, headers, Elebrock intake and carb, no lock up TB350 transmission it use to get 8 MPG. The engine going down the highway was always running high rpms and would climb most roads without ever down shifting. I replaced the...

    Aftermarket EFI

    I read and read as much about after market TBI like Holley sniper, Fitech, ect as I could stand. I have a 350 Pace Preformace GM truck crate engine in a 78 GMC 4x4 truck. I spoke with a couple of high performance car builders in the area that also have their own Dyno. They seem to prefer...

    NV4500 problems finding clutch set that fits

    Here is the scoop on this problem. The standard clutch does fit. I had a small bur on the spline that I did not see that caused the clutch not to fit. I did how ever purchase a clutch that would not fit my SM465 that was machine too small which got me going in the wrong direction. Live...
