    Temperature gauge

    I need some help on this one. I bought a 1986 c10 305/th350 Silverado 6 months ago. The temp gauge goes cold to overheat randomly, nothing in the middle. I did the easy thing first and swapped sensor. Same thing. Today I swapped the printed circuit and gauge while it was out. I have the same...

    Passenger side running lights bright

    Good evening everyone, Before I dive deep into some electrical diagnostics, I’m hoping with all of your combined years experience with our trucks, some of you may have run across my problem before.

    Fuel tank selector valve

    Hey everyone, I have a 1986 C10 with fuel tanks. The selector valve let go in my driveway (lucky me) and I purchased the Autozone fsv2k (6 port) valve as I have a return to both tanks. It comes with a pigtail to wire it. The factory pigtail seems to match up in shape and size but do the pins...

    Post 87 5.7 blocks

    I’m on a hunt for a 350 block to build for my next winters project. I want a one piece rear main. My truck is an 86 c10 with a 305. Will the post 87 blocks drop right in or am I stuck with looking for an 86 with a one piece rear main? Thanks in advance.

    Temp gauge

    Hey everyone, new to the forum. I recently purchased my second 86 c10. The temp gauge isn’t working properly. It pegs all the way cold, then all the way past hot with no rhyme or reason for it. Either way it’s not accurate. Short of checking continuity in the wire, any other things you have...
