    Best Choice for Drivetrain

    I have a low mileage 1976 K10 shortbed. It has a 350, TH350, NP203 and 3.08 gears. I need more lower end torque, the reliability and efficiency of fuel injection and would like to be able to comfortably drive it down the road at highway speeds. Everything is stock except for headers. I have 32"...

    Aftermarket EFI Recommendations

    I'd like to convert my 76 K10 to EFI. The systems I have been considering are the Fitech, Sniper and Edelbrock Pro Flo. Does anyone have any real world experience installing and using these systems and can provide recommendations? I was quoted around $1800 for the Sniper kit including their...

    Engine Maintenance

    I have a stock 350 engine in my 76 K10. I have a coolant leak at the top of the engine and I was planning to replace the original water pump, thermostat and gasket, as well as the intake gaskets. While I was there, I thought I would do some updates. Does anyone have recommendations for a good...

    Transmission Tunnels

    Are all K10 transmission tunnels bolted in? I have watched a number of videos for replacing floor pans on these trucks but I do not remember seeing a bolt-in transmission tunnel.

    Engine Choices

    I'm building a 1976 K10 shortbed to sell. I'm trying to decide the best engine to install for resale. Would people be more interested in an LS (LQ9) or a big block paired with 4sp automatic? What would bring the best return on investment? Thanks...

    Choosing a Powertrain

    I have a 76 K10 shortbed fleetside that I am building (restoration with small modifications) for resale. It has a 2" lift and will run 32" tires. I am looking for a good combination of engine, transmission, transfer case, and gear ratio. The original 350 engine will either be rebuilt or...

    Fuel Filler Parts Recommendation

    I have a shortbed from a 1986 C10 to put on my 1976 K10. I would prefer to keep the gas door rather than the stock round hole type. Due to corrosion, I need to replace my tank, sending unit, mounts, hoses, hardware, etc. It seems there are differences between the the year models 79-87 that had...

    AMK Bolt Kits

    Due to the extensive rust on my vehicle, I have found a number of bolts that I could not save. I am not necessarily going for a period correct restoration. I notice AMK Products have different types of kits available: button head stainless, button head polished stainless, hex head stainless, hex...

    Rust repair - order of replacement

    On my 76 K10, I am prepping to replace various panels that were riddled with rust. I am not able to replace the cab so I will have to work with what I have. I have to do inner and outer cab corners, floor pans, inner and outer rocker panels, cab floor mounts (not the main supports), and kick...

    Differential Advice

    In my 1976 K10 which is used only on the street and sometimes for pulling a boat, I have the D44 and a 12 bolt rear. I plan to change the gear ratios to 4.10 and install a 4sp automatic for highway use. Would it be worth it to change the rear to a 14 bolt SF that already has a 4.10 ratio? There...

    Gear Ratio Selection

    My '76 K10 has the original 350/350 and NP203. I plan to upgrade the drivetrain but I need advice on what gear ratio to use. The current gear ratio is 3.07 with a Dana 44 and a 12 bolt. I will be installing a 383 pushing about 420 lb ft torque mated to a 4l80e and an NP205. I will be running 33"...

    Painless vs. American Autowire

    I need to replace the wiring in a 1976 K10 and I plan to add AC, electric fans, different gauges, etc. I do not necessarily need a stock appearance but I would like something that is easier to work with. Besides the cost difference, what are the benefits and drawbacks when comparing both systems...

    Shortbed Floor

    I have had difficulty finding a shortbed fleetside steel floor. None of the normal vendors (LMC, Brothers, Classic Industries) has it. They say it has been discontinued. Jegs allowed me to order it but so far it has been backordered for over 6 months. Is it possible to put a wood floor in it...

    Choosing engine for future flip

    I have a 76 K10 shortbed fleetside with a 350, TH 350 and NP203. I need engine work and I would like to upgrade to a 4sp auto. My plan is to eventually flip the truck. Which option would bring me the most value when selling: building the original 350 for torque or getting a big block? My plan...

    Heater Control Panel Question

    My 1976 K10 did not have AC but I plan to get an aftermarket kit next year. In the meantime, I need to get through the winter with heat. My current panel is broken and unusable. I have access to two used panels, one from a 1977 and one from a 1979...both with AC. Can my cables be connected to...

    Used Replacement Cluster

    I need to replace some components of my gauge cluster in my 1976 K10. I found a complete cluster for a 1977. It has a clock and my original does not. Is there wiring in the dash to account for the clock or is it directly wired by the printed circuit? The gauges for both sets are not in the...

    Speedometer Does Not Work

    I've spent the last hour trying to determine why my speedometer doesn't work. It hasn't in quite a while. I have replaced the cable. I can spin the cable from the transfer case end and the speedometer does work. There's a part sandwitched between the cable and the T-case housing and I'm not sure...

    Stabilizer

    I need to replace my stabilizer and I plan to stay with a single. I've seen the ones from Rancho, Tuff Country, Rough Country, Skyjacker, AC Delco, etc. Does anyone have any recommendations? It's been difficult to find reviews. Maybe they are all about the same. The truck is a 1976 K10 with a...

    1976 K10 Washer Issue

    I replaced my wiper motor with one from a yard. I connected it and it parked the wipers but did nothing else. I grounded a wire and it began working so I determined it was a switch problem. I just received a NOS switch from Philips Muscle Car and the wipers work fine. However, the washer pump...

    1976 K10 Fuel Filler

    I have to replace my right bedside due to severe rust. I also have to replace my gas tank for the same reason. I would prefer having a gas door rather than the cap that installs in the side of the bed. Looking at the parts diagrams on LMC, it looks like the bedsides with doors have a different...

    1976 K10 Wiper Switch

    I've been trying to diagnose the wiper issue. I can get the wiper motor to work by grounding the right terminal at the motor connector. So, it looks like it may be the switch. I've removed it and found a lot of corrosion on the switch terminals. I cleaned them and reconnected it. Nothing. I...

    Sheetmetal Compatibility

    I have the opportunity to purchase two used doors from an 1986 c10. Will they fit a 1976 K10? Other than the front clip, is the other sheet metal compatible between the two years? Also, has anyone converted the passenger side round hole gas filler to the square door? What would be needed for...

    2" Tuff Country EZ Ride

    I am considering this lift for my 1976 K10 build but wanted to know what I would need to add besides the kit. The kit has the front springs, rear blocks, hardware and shocks. Do I need a drop steering arm? Do I need brake line extensions or anything else? It's difficult to tell how the truck...

    350 Engine Build

    Needing more torque from my 76 K10 and with a limited budget, I am considering rebuilding my 350 around the comp cam 12-231-2 setup. I'm looking for a recipe to get me over 400 lb ft of torque. Does it make sense to go with a Vortec setup? If so, what head/intake/carb combinations would be...
