  1. Big block el camino "dry-popping"

    Hotrodding Basics
    I have a mildly built 468, w/long tube headers running a heavier cam & a q-jet carb. When I really stick it on the road, it will kind of bog down on me and pop-pop-pop-pop. (Its also open headers since its too low to run proper exhaust on right now) I reckon it's my fuel pump that's the problem...

  6. Possibly running rich?

    Hotrodding Basics
    I replaced the problematic 800 cfm Quadrajet on my Chevy 350 with an Edelbrock 1405 600 cfm carburetor. Right away I noticed it starts and runs much better and sounds healthier, but the fuel economy REALLY suffers. With the q-jet I had been getting about 9.5-10 mpg w/ a max of 10.6. Now I'm...
  7. Runs great off idle; bogs when floored

    Engine
    454 with Holley carb and mild cam. Backed by a TH350 auto. If I floor it from idle, it takes off and runs up through the gears fine. If I floor it from a roll at, say, 2,000 rpm, it revs a few hundred rpm and then bogs badly -- feels like the engine cuts out for a few seconds (feels like a...

    Where is the best place in a new gas tank to put the return line ? I have seen that it should go in the top , I have also seen people say it should go in the bottom. Mine is in the bottom at the back of the tank, right beside the outlet. Will that cause a problem ??
