    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...

    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...

    Well! Once again again again again I'm messing with my Holley lol. I need help and this is the place to go for answers. Holley 670. I have done a lot of different things to it to get it to run right, and I've had it dialed in very well. I figured out I need adjustability in my Idle Feed...

    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 ??

    I was told years ago never to fill up at a gas station that was filling up their tanks. Is this true. I was told it stirs up all the junk in the in ground tanks. Any thoughts?
