    Holley Sniper EFI fuel economy

    So I picked up my truck with a sniper EFI already installed on a 350. Call me greedy, but I wouldn't mind getting better fuel economy out of it. I ran down all the usual suspects and it doesn't appear to be running rich or lean yet I'm averaging approximately 8-10 mpg. From what I've heard that...

    C10 to K20 Body Swap – Driveline Issues

    TL;DR: I'm in the middle of body swapping a 1985 C10 cab & bed onto a 1984 K20 frame. The frame was purchased without a front clip, engine, or doors so specific truck options are not known. After decoding the VIN I confirmed the donor truck/frame is a Canadian truck that had a 6.2L diesel, and...

    1982 C30 custom deluxe single rear wheel

    hey I’m new here and I’m really trying to find out more about my truck. It’s a single rear wheel 1982 c30 (supposedly) with 4 speed Manual and a 350 under the hood. It used to be a refinery truck so it did a lot of idling in its life. But I am curious, when I look up the VIN it says it’s an 82 1...

    Replaced gaskets, now it won't start

    About a month ago I started the process of going through and replacing gaskets/filters in my 1975 GMC C1500 (350 engine). I finally got it put back together today, put fluids in, and reconnected the battery. When I went to start it up, nothing. The interior light didn't come on, the dash didn't...

    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...

    Can you make a 305 stroker with 350 crank and rods?

    As the title says, can you make a 305 stroker with a 350 crank and rods? What would it be? Would it be a 327, or a 340, or is it even possible? I havent done any research, just dreaming here. I have a 305 that wrecked the crank and rods, and I have a 350 that is dead, but the bottom end is...
