    help me find this ticking noise on my truck ( 1978 Chevy C10 305 )

    hello, my Truck has this weird ticking noise. I tried to adjust the lifters on my Truck. so I try to tighten them, but no matter how much I tighten the lifters it was still ticking very loudly. I assumed that it was something wrong with the pushrod itself or it is something else entirely. I...

    Long tube headers installed, now backfiring on deceleration?

    So I finally got around to installing my long tube headers today. I removed the rest of the exhaust including muffler for now until i can find a place that can weld me on some mufflers. It runs fine (loud as hell) when i step on the gas, but as soon as i let off the throttle, it backfires like...

    New motor... from 250 to 350

    I ran across a good built 350 for $1000. My truck is a base 6 cylinder 1981 that runs good, on an original 6 cylinder with 80,000 miles on it. I'm the second owner and bought from a friend who was the first. So, if I get the motor what upgrades must be done... Tires, wheels, rear locker in my...

    Engine problem

    I’ve got a 350 with a turbo 400 trans, it’s having trouble starting and ides high sometimes, also when a load is put on it backfires and won’t downshift. Anyone else had a problem like this? the engine has a smog pump which I think might be the problem or the carb

    Free power mods on 305?

    Does anyone know how to squeeze any extra power out of the 305 in my c10? Like is there something I can adjust with the air intake or something that'd make a difference? Also I'm not necessarily looking for any huge improvements (I mean power costs money lol) but like even 5 more hp would be enough

    Opinions on an Engine Swap for 81 C10

    Right now, I have an extremely tired 305 and I'm ready to swap it out. Now I've bounced around different ideas, but not sure on which route to take. I think I've narrowed it down to wanting a 350. I don't want to do LS swap or big block. I've done some research and I've come down to: 1. Buy a...

    Engine Misfire/Shutoff after just 30 minutes of driving

    Hi All, I have a 1987 C20 5.7L 350 Longbed, with around 50,000 original miles on it. I have been having this problem for 2 months now, and it started about a month after purchasing it. I don’t know a lot about trucks, but i’m learning. The first time it happened to me i was on the freeway...

    Another cam thread... But maybe not the usual.

    I'm no stranger to building playtoy engines and putting together a performance package pretty well. But this time around I'm goin the other direction for as much torque down low as possible with good fuel economy. The project in question this go round is a 1980 c10 with the dreaded integral...

    Bought a 1986 K10, truck died while driving today.

    Hey folks, just bought my first square body truck and joined the forum. I'm 17 and also have a 1978 Corvette that I have worked on quite a bit so I have a decent understanding of 350 small blocks and decent idea of how to diagnose issues. Today as I was driving the truck, it died on me. After...

    Horrendous gas mileage issue.

    So I have a 1985 gmc k2500 with 4x4, 350 and an edelbrock 1406 on it currently. I had a 1906 till they kept failing. Anyways this truck gets about 5 mpg, which I know is gonna be common, but I feel its still excessive. Any thoughts how to fix it? Note 1. I got this truck when my dad passed...

    Chevy 250 Exhaust Manifold

    I've looked around and can't seem to find any information so hopefully y'all might now. Has anyone seen this exhaust manifold before? I know people make them custom but I don't believe that is the case with this. If someone does know, is it true dual or just dual output? Eventually looking...

    rear main seal

    I've got a 350 engine from a 1981 c1500 that I'm planning on putting in another truck. The engine has 24,000miles on it. The truck it was in was sitting for a few years,but runs awesome and doesn't leak. While the engine is out, I want to spruce it up and change some seals anyway, should I...

    Conquered Initial Problem, Followed by New One

    A lot of you guys helped me out with an overheating problem originating from a bad water pump seal and I thank those of who you helped me out. I now have a new problem. My truck will at times, seemingly random, misfire. The carb misfires when it’s cold and I get on it - but this thing is...
