    No power up hill or after 45 MPH

    This is really the first time I've driven it since I've had it. I had to do a good bit of work to it. I don't think it's the exhaust, I just put the exhaust and the headers on. I just don't understand why at low speeds it runs great until I'm on the highway and hit a slight grade. I loosened to...

    No power up hill or after 45 MPH

    I'm trying to figure out why after about 45 mph (give or take) or even at a slight grade, I struggle to keep moving. Even on a flat grade, I have the pedal floored and I can barely make 55. I just change my plugs and wires, my fuel filter. And yes it is installed the right way. I'm thinking it's...

    Turn sign issue

    I grounded it a couple of ways, even to the battery. Looks like I'm drawing power from somewhere else because it's affectin my tail lights and making them dim. Looks like I'll have to sift through the harness to see

    Turn sign issue

    Anyone know why my left side turn signal won't work at the front of the truck when I turn my lights on? And when I turn my right side signal on, the back marker light turns off. Everything works fine till I turn my lights on. Like I said, it's only the left side. It sounds like something is...

    Wiring has me at a loss

    All of my turn signals and everything were working fine. I tried putting in bulbs for my two front turn signals and I had a hard time getting them to light up. for a second they worked, then they went out. now all of a sudden, my running lights will not work at all. I used a tester light and...

    Not sure where oil is leaking

    My oil pressure gauge still works. so I was thinking I'll take it out and put a little RTV on the threads as long as they look alright

    Not sure where oil is leaking

    Well it definitely looks like the oil pressure switch. I'm almost 100% sure it isn't the valve cover gasket and it doesn't really look like the intake manifold from what I can see. I guess All I can do Is fix that and see if it still does it. But would that really make it leak that much just...

    Not sure where oil is leaking

    I'm glad it isn't something real major. Shouldn't be too bad to change. Thanks a lot!

    Not sure where oil is leaking

    Hell, I didn't even think of that lol. My first thought was it's probably some major oil seal on the motor, knowing my luck lol

    Not sure where oil is leaking

    Or maybe oil pump? I don't know why it's dripping on both sides though

    Not sure where oil is leaking

    I just noticed a motor oil leak I have dripping right in front of the tranny pan on both sides. the truck doesn't have a flexplate cover on it so I'm not sure if it's running down the block from the black of my valve covers, where I can't see, or maybe I picked up the wrong oil filter by...

    Under the grill trim piece

    Good afternoon guys. I was wondering if anyone knew what this piece is called. It goes under the grille and attaches to the fenders on each side with two bolts. Mine was already broke when I took it off and I wasn't sure what it's called to look for a new one. Thanks in advance

    Single headlight to dual headlight conversion

    Yea I am. whoever had it before me put an 82 front clip on it. I ended up having to replace both fenders, inner fenders, and core support. They let it sit out in the grass and that just killed it. It only had the single headlights but I bought a dual headlight core support and it looked like I...

    Single headlight to dual headlight conversion

    Hey guys, I'm switching from the single headlights to the dual and I was curious if the headlight buckets and headlights are the same size as the single headlight or if they're smaller. My adjustment screws in buckets just won't seem to match up right with the clips. My guess is because they're...

    Not sure which core support to buy

    Yea I've got an old parts truck I can get all of that from. I'm not sure if I wanna go to the quad setup right away. I kinda like the single. I'd just like to have the option. It was only a couple of bucks more

    Not sure which core support to buy

    Alright I figure but I just wasn't sure. Wanted to be 100% before I went and bought something. Thanks

    Not sure which core support to buy

    Hi guys. Wasn't sure where to put this question so I hope this is the right place. The previous owner let this truck sit in a field and that ended up rotting most of the bottom of my core support. The truck is a 78 but it's got an 81ish I believe front clip. So would I need to buy a core support...
