    need new carburetor

    I don’t want an Edelbrock. They are square bore, whereas the Quadrajet is a spread bore, which means two things: 1. The primaries are the same size of the secondaries, so you don’t get as good fuel economy. The Quadrajet’s primaries are smaller than the secondaries, so if you stay out of the...

    17066559 ...& it has the stupid double D air screws. none of the auto parts stores carry the tool to adjust them. I had to pay $50 off the Snap On truck for a cheap piece of crap tool that was not strong enough to turn the screw and when I applied pressure to it, it broke..! I have called...

    starter wires routing

    1986 GMC 1500 Sierra Classic 305” 700R4 I noticed that the positive starter wires are routed between the block and the exhaust manifold. I feel that this is a rather bad placement for this wire routing. Am I the only one that feels that the heat created in the small space is...

    water pump, Alaska 86 GMC Sierra classic 1500 4x4

    My 350’s water pump was leaking out the weep hole, so I bought a remanufactured water pump and installed it. It wasn’t until I had everything back together, that I noticed that the pulley scraped on the pump & fan studs only fit backwards. I wasn’t exactly happy, but I managed to MacGyver it...

    Alaska; 86’ 4x4

    Can anyone help me identify my 700r4 transmission? I'm curious about the lock-up activation circuit. The Canadian” 350 engine came out of a 80’ California, 1 ton van. The carb didn’t come with this engine. I’m just trying to get the best mpg possible.

    Alaska; 86’ GMC Sierra Classic 1500 4x4 swb

    i assume that, when you speak of this “converter lock”, you mean, the transmission, when you use words like “solenoid” & “current”? i wonder if this “locking converter defeat” thing, is why my truck lurches at stop signs or lights, when it’s still a little cold? i’ve no idea what year my...

    Alaska; 86’ GMC Sierra Classic 1500 4x4 swb

    I have been unsuccessful in finding a complete heat stove, nor a working air cleaner housing. I can find a new heat stove valve, But not the housing. I suppose that I will have to find a used one or fabricate one. I found a few air cleaner housings, but none with a functioning hot air...
