I agree 100% with Davis
Every carb and motor setup is different but IMO try anything from 154 to 168 in that Rupert

Have had a mechanical pump every since. I do not believe you need that bid of jet with an Enderle pump.

I have a mechanical pump at home and if I had a cell up front I would run it in a heartbeat. I have made my own throttle body to run injection but haven't gotten around to putting it all on yet because of the amount of work it will take to put a cell in the front of my roadster and to mount the pump. Just not much room there.

I don't know why it's so hard for some of you to understand that some of us, myself included, have absolutely no room up front for a fuel tank without some MAJOR modifications. If I did I'd be running a belt drive pump but I don't so the electric is the only way. But if you look at the times I have posted in my sig I don't think my car is hurting any.

Zip,
I've seen the surge tanks set up just like what you are describing. I make our own aluminum cells and sheetmetal valve covers that I used to sell, so making the tank and getting it set up is not a problem. I understand what is needed (although I appreciated the intended help). I don't want to add the weight and complication just to run the injection. I will add a frame for the cell and aero nose to the front to cover it when I decide to inject it, but don't want to do it until racing season is over. Thanks for the reply.

Why is it that you think you have to have a fuel cell up front to run a belt drive pump? Remember it is a carbuerator with fuel bowls not injection. I now run a 1250 Bolaws with a Bolaws belt drive pump with a bypass built into the pump. I dont even have to use a return line. My fuel tank is 10" from the pump. My point is you said you have never ran a belt drive pump yet you continue to tell us we are wrong. My car runs 4.70,s and will repeat againand again and again will yours? Does that make me right,NO!!! What makes me right is that i have experience running an alcohol carb with a belt drive pump. Do you bracket race or race heads-up.

Davis,
I never said you have to have the fuel cell up front to run a belt drive pump, but as you know these were not made to suck from the back of a car. My cell is a lot further from the pump than 10". Is your cell in front of or behind your pump? I do remember this is a carburator with bowls. I never said I have never run a belt drive pump! I AM IN NO WAY SAYING YOU ARE WRONG. I just agreed with George's point when it comes to way carburators react on different size engines. I am seeing these results.
There are 3 cars that I own part of and race. All bracket cars, '66 Nova with Ron's toilet sbc, Victory dragster with belt drive pump and carburator 468, and my '27 roadster with electric pump and carb sbc. So I do have experience running all three combinations. I'm glad you car will run 4.70s, I truly mean that. But I also don't care. You do have a nice looking car and I'm sure you are happy with the way it runs. My car won't run 4.70s but that doesn't mean I'm an idiot about this stuff either.
I don't understand your reaction to the things I have posted because none of it was directed at you personally. I know there are different ways to do just about everthing and get good results. Remember I am not saying you are wrong only posting my opinions, surely nothing for anyone to take offense at.

Curtis, This post was not meant for you it was meant for George, my mistake i should have adressed it to George,Sorry! I have plenty of friends who run belt drive pumps with the tank in the rear of door cars with no problems. One friend of mine runs a 56 Chevy with a 468. Rupert 1050 and enderle belt drive pump with 144 jets and i have seen him repeat 6 and 7 times in a row. Hell i have seen him repeat to the thousand 4 times in a row. Again that post was not meant for you. It is your car and you can do whatever you want with it. I just didnt like George telling me i was wrong when i run the fuel system you were asking about and he does not. Thank You, Don
