    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.

    Mr. Gasket Headers

    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.

    Intake plenum gaskets

    Show us some pictures of your K20 and the 400, please. We can probably "practically fix it" (everything but the work) with a little more info. Then you can go to your mechanic and tell them what you want done and why.

    Finding Serpentine Belt Lengths

    I just went through this. Trial and error. A few MMs makes a big difference. Take the belt that you have, and the measurement you make with the measuring tape, and try to figure out which one you need, see what the parts store has in stock and get the closest one and go try it out. If its the...

    Sanderson BB8-P headers on a 454 in a crew cab dually

    I've got a set of those headers on my SHOP FLOOR. I don't think that they will fit on anything, but the break in stand. (I fell for it too) I just used the stock manifolds, and they work great. No burnt plug wires, header leaks, etc...

    Brake Booster Vacuum re-location?

    Run your brake booster to the one on the back of the carburetor and get a combination vacuum fitting for the manifold for the PCV, heater control and automatic transmission. Get a short one so it clears the bowl on the carb. You may need a spacer under the carb. Something like that.

    Transmission grinds going into L or R

    If you are not moving, with the clutch in, they should not grind. If you are trying to get it into L or R with it rolling, they will probably grind a little. If they grind when you are not moving, your clutch will probably need adjusting or replaced.

    Transmission grinds going into L or R

    So your truck has the 4 speed overdrive transmission ,NP A 833, or the 4 speed with the granny gear low? SM 465

    Speedo cable length for 81 c10 6 cylinder saginaw

    I just bought one from O'reillys and it was the right length. Works great and was only like $13. You might give them a try.

    Trailering your square body

    Make sure that you have good tires on the trailer. Load it up and go. It sounds like you have a good truck for the job. Take your time and tie it down good, so it doesn't bounce. Hope for the best, be ready for the worst. Do it now, before it gets too hot, and it will be easier on you and your...

    K20 454 truck engine build

    Don't "over cam" it. You will be happier in the long run with something on the "smaller" side than something real long on duration. Melling MTC 6 (good old fashioned RV cam) looks good for a 4 x 4. The "268" advertised duration cams would be the "biggest" that I would use. Off idle grunt, up...

    Remove accessories from this old truck?

    The suburban looks good, the yellow truck is a little bit impractical. I'm not sure which vehicle you are working on or asking about.

    Power steering fluid .. what type ?

    I guess that I learned something on this one... I don't have any classic vehicles with automatic transmissions, so I will stick with the power steering fluid. Thanks for the education.

    Power steering fluid .. what type ?

    I use power steering fluid for power steering. I have had bad luck putting ATF in power steering pumps. There must be a reason that they call it power steering fluid and the other one is called automatic transmission fluid. The front of the container tells you which fluid goes in which system. I...

    distributor removal

    It makes it easier to put back together. Like Hucked said, that is a good thing to start with, before you pull the distributor, put it on TDC, or at least real close.

    1981? 350 in a C20 - Vacuum/sensor questions

    Vacuum advance, heater, pcv, brake booster. That is about all you need. All that other stuff is basically ways to regulate the advance and warm air, I think. Lots of little parts to replace, if you have to have them.

    Wiper Blade size

    I use the ones that the book says at the parts store. It rarely rains here, so I never gave it much thought beyond that. They usually just sun rot and when it does rain, you have to look through a spot that they miss, or go buy new ones. But next time, I will think about some longer ones, maybe.

    95 Chevy water in passenger floor board

    Heater core. Mine was dripping out of the bottom of the cab. I had to loop the heater hoses... for now... Its warm enough, no heater necessary for another 6 months. The carpet is dry but kind of oily now.

    edelbrock avs2 650

    I have to pump mine about 20 times to start it cold. When it is warm, usually have to pump it a couple of times. It's not fuel injection. 1406, Edelbrock pump, air gap intake. For some reason they just wont hold fuel. I guess it evaporates. So I would say that yours is "normal".

    tighter steering

    If you think a C20 is hard to turn sharp, you should try a K30 with a Dana 60 front axle... It makes a K20 seem like a sports car. Like Hucked said, Nature of the "Beast".
