    How do I test mechanical fuel pump

    When I go to start the engine it'll crank and crank and crank and I have to add fuel to the carburetor and then once it's running then it'll stay running but I haven't tried driving it that way because the fuel filter remains practically empty

    How do I test mechanical fuel pump

    I have a 1978 454 it's in a 1980 GMC k3500, I may need to change the fuel pump so I'm asking who makes a good mechanical fuel pump for this engine? It has a fuel return on it

    Steering dampener

    It's just a stock height truck with normal tires, but I replaced all the tie rod ends and figured while I'm at it I should replace that shock

    Valve adjustment

    When I adjusted the valves in my 78 454, the engine was running and hardly any oil was spraying out the driver side but when I went to do the passenger side there was a considerable amount of oil spraying out of there, why would there be such a difference between the two sides? I'm just curious...

    Timing marks

    I have bought stuff from harbor freight over the years ever since they became a hardware store, some of their stuff is junk but some of their stuff is really good and comes with a lifetime warranty. I bought ball joints separators from them and broke them within a couple of uses took them back...

    Timing marks

    I understand the damper ring does slip over time I experienced that with the Pontiac 455 many years ago. What should the timing be set on this 1978 454? The trucks a 1980 k35 with the standard transmission.

    Timing marks

    We rebuilt the engine a few years ago, replaced the timing chain with a double roller so it's fairly new. But I will see.

    Timing marks

    Zero is where the big zero is punched into the tab to the right, makes perfect sense to me!

    Timing marks

    This is a picture of the ignition timing tab on my 1978 454 it's in my k35 1-ton dually, I am trying to identify the timing marks on this factory bracket but unfortunately the numbers are heavily worn, would anyone like to take a guess at which notch is zero top dead center and what the other...

    Front Windshield

    I had a glass company to come right to my house, they were done in about 40 minutes, he took out the old windshield and seal and replaced them both and it turned out pretty good for $300!

    454 valve adjustment

    At this point I'm not real sure what the ticking sound is, I've heard enough valves over the years that it sounds just like a rocker arm, but then as the engine starts warming up there's also the sound of a light metallic scraping noise that comes louder and louder. And not terribly loud just a...

    454 valve adjustment

    I have this 1978 454 it does not have a lot of miles on this engine since it's been rebuilt but I hear light ticking and clacking coming from the right side, I haven't ran it yet since I pulled the valve covers off but I'm going to do that soon, are these rocker arms adjustable or are they the...

    Ignition cylinder

    I know the truck has a glass fuse box because I have the redneck brother-in-law that used the 22 shell cartridges a fuse, but I just remembered it did have an automatic transmission and my brother must have changed the steering column, and if that's the case the steering column is out of the 78...

    Ignition cylinder

    The last cylinder I purchased from Amazon has the spring loaded retainer, it snapped and locked right into place! Thanks for everybody's help! This one my dad's truck he bought in 1980 from the factory and I am trying to repair a few neglects so that it can be comfortably driven. These neglects...

    Ignition cylinder

    I found this one on Amazon and it refers to fitting the models without the retaining screw, it seems to appear identical so maybe I need to try this one?

    Ignition cylinder

    I'm not sure but it might be the 1978 design, look at the lock cylinder on the top it has a notch cut out of it I'm assuming that's where retaining screw goes to hold it in place, but if you look at the box cylinder below it there is a protruding tab type thing that I've circled I believe that...

    Ignition cylinder

    Where the arrow points too is what looks like to be a slot with the flashing still closing it, and it seems to line up with a tab that's on the old ignition cylinder, this slot would have had to have been opened up to depress this button to release the cylinder, the newer cylinder doesn't have...
