BB 454 Fuel Pump

[55 Tony]

I run an old Eldebrock Mech on my 396 with 1/2 inch inlet and outlet and 1/2 line all the way to tank which is the original 1955 tank with a rear facing sump. A Holley regulator splits the line to each Holley 600 on top of tunnel ram. No fuel starvation issues.

Are you serious ... 1/2"? At first I was running the original 5/16 and when I put in new 3/8 line and pickup I didn't notice any improvement with the fuel starvation problem. I've never seen a 1/2" pickup for our cars, just 5/16 and 3/8. I don't think I ever had any fuel starvation problems when running a Holley either with their large bowls. Q-jet is a different story.

Well, trying to run 12 sec quarters on lightly traveled roads is a good way to end up on the 6 o'clock news, and just plain irresponsible. Zero-60 runs in an isolated area is barely acceptable, and will tell you just as much as you need to know.

Zero to 60 is barely acceptable? Even when the speed limit is 70 and I don't get anywhere near any other vehicle. Actually if you pass a state trooper doing 80 they don't bother with you. Yes another 35mph is a lot but I really don't see who it could hurt besides myself and how is it more safe at a track?

Never mind, I give up, that all makes perfect sense with a 63 year old car. And at the track, they have emergency personal on site.

I have a sender unit with the gas line blocked off, read my post again tank my tank has a custom rear facing sump with two 1/2 npt rear facing outlets. when I launch gas is forced toward tank outlet. As far as float bowls I have 4 of them to feed.

The only reason a Holley would do better than an Edelbrock or Qjet is the float bowls hold a little more fuel. But not much more. You'll still run out of fuel in less than 1/4 mile if you have pump or restriction problems.

Yes, that info about the tank didn't sink in. And the split to two, I was thinking bowls, not carbs. I'm guessing you're only doing 1/8's, or awfully high speed 1/4's. What kind of times?

Good. Nobody asked for your safety lecture in the first place.

I have only made passes at flag drags see link, the one time I showed up at a 1/4 mile track I lost the front yoke and u-joint on starting line. I have two purpose built Camaros that run 10s and 11s with minimal effort and just routine maintaince. My BBC Camaro has #10 or 5/8 fuel line from cell to regulator.
