    Big block running hot. Can’t figure out the issue

    Show us some pictures of your set-up. Mainly the serpentine set up.

    82 Sierra Grill alternatives

    Repair it, and repaint it. It is not missing much at all.

    Can’t find a heater core for my c20 suburban…

    That looks like a non A/C truck? Probably any parts store will have one. I got one from AutoZone for mine recently, although it is an A/C truck.

    350 small block

    I think that all Edelbrock carburetors have this problem. they don't hold the gas in the bowl, overnight. It must evaporate or something. I am not sure if this happens with other types of carburetors. I usually have to crank it for a few seconds, then pump it about 10 times, then repeat a couple...

    Potential wiring problem

    I dont think that '83 trucks "think". They don't have computers that would provide overheat protection, prevent it from starting, no matter what the gauge says, or if it even is hooked up. Maybe you are having other wiring issues that are preventing it from starting.

    350 or LS

    350 SBC. LS swap is cool, but a lot involved for not much better gas mileage. Don't make it more difficult than it already is going to be getting that old square back on the road.

    Slow Climb To The Top

    On a TH400 there is an electrical switch that goes through the case near the valve body. I don't remember exactly, but it hooks onto something under the pan, and that controls the kick down. Maybe unhooked or needs a replacement switch. Its been a few years since I had a TH400, but I drove it...

    Aux battery for audio

    I remember that you have to use two of the same sized batteries for it to work.

    Swapping out OEM distributor with HEI distributor

    Are you sure that only the 305 came with the electronic HEI? Both my Big block truck and my 350 small block truck have those wiring harnesses hanging there doing nothing.

    Just picked up an LT4 swapped '86 C10

    What is an LT4?

    327 vs 350 for a daily driver

    Either will do about the same, but good luck finding a 327. Go with the good old 350, SBC. No substitute for cubic inches.

    Fluid Changes

    I think he is asking a serious question. There is so many different oils. In all of my flat tappet, gas engines, I run Valvoline VR1 20w-50. Good for everything about a square. Plenty of zinc for the cam, heavy enough for the high rpms and heavy loads. Here we go...

    1969 427 into 77 C20

    Go for it! It will drop right in. Use small block motor mounts to match the holes on the truck frame. You will need some big block brackets.

    Edelbrock 750 cfm or 600 cfm carburetor for 454 stock engine.

    The 600 will work better for what you are wanting. Make sure it is clean inside, floats set correctly, jetting set for altitude that you are at. Edelbrock manual has all the info. Make sure that you have a return line to the tank to prevent vapor lock. Maybe put a plastic 1/2" spacer to help...

    Where to buy LS motor?

    It sounds like the LS swap is out now. Back with a good old SBC?

    Small block be big block engine pedestal

    The big block will bolt right into the small blocks place. Buy the small block motor mounts for the truck, not the ones for the big block motor. Show us what you are working on.

    Carb at high alt

    It could be those electric fans restricting air flow through the radiator. Did you get a good old fashioned manual temperature gauge on there to make sure that the factory gauge is correct?

    Carb at high alt

    Leaning it out will make it run hotter. Maybe your radiator is not flowing well, or you dont have a fan shroud. What thermostat are you running?

    Carb at high alt

    Like Rustisbest said, it will depend on if it is a 1405 or 1406, but probably at least 3 stages lean. At 2000 you should already be at 1 stage lean, so maybe plan on making a rod change once you get up in the mountains. Try to figure out which rods you will need to change to without having to do...

    2.5" or 4" Lift 1986 K10

    You may need to do a little trimming on the bottom rear of the front fenders, if you lower it. The front wheels will rub and rip the chrome off, when you turn. I would leave it like that, it looks perfect. 1-1/2" isnt much of a difference.

    Power steering too slow?

    Hydro bind?? On my hydro system, the rpms have to be higher than idle to get the wheels to turn easily. I assume this is hydro bind. It seems like a larger diameter pulley would make the pump turn faster at idle and prevent this. I just have not found a larger pulley for my serpentine belt...

    Front bumper opinion on position

    Yes, I clicked on the image. It doesn't get much bigger on my PC. Oh well, I guess I can't help.

    Front bumper opinion on position

    Hard to tell anything, the pictures are so small. Show a good, full size picture of the whole truck.

    Power Steering Woes

    There is a few different reservoirs for different configurations of accessories. You probably need a different reservoir with a cap on that set up. If it has hydro assist brakes it needs one with two return ports. Some look the same but have the returns pointing the wrong way, some are a little...
