    New to pickups & fifth wheels

    I love my squares, ( and "hate" EFI & computer controlled) but they are limited. A big fifth wheel trailer will take a big diesel, modernish truck. Or just get a smaller trailer. They aren't designed, engineered or built for more than about 9-10,000 lbs of load. (see Keiths table above). Its not...

    Does anyone make 17" aluminum 4x4 Rally wheels?

    What do they look like? I am just curious. I assume that you are asking about 1/2 ton 6 lug or 5 lug. I am looking for some cool looking 16's in 8 lug.

    Making sure inverted flare cooler lines seal

    The threads don't seal, the flair seals. Trust the engineers. Don't over tighten.

    Blower motor date codes?

    On a rare 60's Camaro it would be a thing to have, on a 70s square body, whatever the parts store has. Not many would probably give it a second thought or look as long as it works. Why are you asking?

    Some hesitation and stumble 85 k20

    HOLLEY carburetor, VORTEC heads and snow in the picture. I dont think the heads don't have a heat crossover. That could have alot to do with the problem. Sounds like it needs a good tune up as well. Just some thoughts.

    396 with Edelbrock 1406 running issue

    All the basics: Bad gas, dirty carburetor, fouled plugs. They all go together. Also the contacts on the distributor cap and rotor can get corroded, especially the aluminum ones.

    Mirror quality question

    Show us some pictures of the mirrors so we can all know what you are talking about. I bought some cheap plastic chrome ones a couple of years ago, for my GMC, and they fit pretty good and look cool, but they aren't level. The original stainless ones on my K30 are much better. I just had to...

    Cooling Questions and Concerns

    The factory GM serpentine systems('88-90 ish) that I am currently using on my Big block and my small block require reverse rotation water pump, fan clutch, & fan blade. The reverse rotation water pump will not have the mount for the power steering pump that the standard rotation has, the blade...

    Intake plenum gaskets

    They are going to work on the carburetor now. Not going to change the intake gaskets. We were discussing reusing the carburetor base gasket. Just to clarify @mucanuc01

    Intake plenum gaskets

    You may need a new gasket. A new gasket is always better, but if the one that is on there isn't torn or damaged it may work fine.

    Intake plenum gaskets

    Yes, take the carburetor off of the truck before taking it apart. Take a few pictures of the linkages and get a magnet to catch the clips and screws when you take them out.

    Intake plenum gaskets

    That looks like what you need, as long as it is the correct one for your carburetor number. It sounds like your fuel pump and lines are probably fine. 6 ounces in 10 seconds is like 67 gallons an hour. I dont think you could burn that much, even with a big load of hay on back.

    Pre internet probably. Not that I know about them specifically, but what info are you looking for? Show us a picture of them.

    Intake plenum gaskets

    That is the problem. Your accelerator pump is not working. The plunger is probably torn or hard or something. The top needs to come off of the carburetor to put a new accelerator pump plunger in it. While it is off and open, it can be cleaned out and sprayed out with carb cleaner. You will...

    86 k5 long tube headers

    Hedmans, Hookers. I have a couple of sets that work on my 4 speed truck. I will look and see if they are marked with a brand name or anything. What did the mechanic say didn't fit about them.

    Intake plenum gaskets

    Cold starting would be more about the choke adjustment and pump shot. If it starts with a primer of gas down the carburetor, that would indicate that it is not getting enough gas. I am thinking it is the accelerator pump plunger, or nozzle is clogged up. That would explain the slow acceleration...

    Intake plenum gaskets

    Nice looking old truck. Did you replace the little fuel filter in the carburetor? All of that sounds like a carburetor problem. Maybe it needs cleaned up again. I can't think of how new intake manifold gaskets will help that problem.
