recommendation for fuel pump

recommendation for fuel pump
I am looking for a Mechanical fuel pump for a big block with 700 HP
I was going to go with race pumps but they do not make them any more. Just parts for them.
I really do not want to go with electric pump
street car pump gas

I fought the same fight you're in. Didn't want to go electric. My advice is forget it. If you're really in the 700 HP range, ain't nothing out there gonna feed it properly. Yeah it'll run fine, but put a gauge in and see what happens at high RPM.
I ended up doing an complete in tank system from Tanks Inc. Best move I ever made. Quiet, lasts forever (supposedly) and I'm good to 1000 HP and fuel injection, if that ever happens. Beautiful factory looking tank, with a built in sump and baffles. Real high end stuff for a reasonable price.
As a last resort ya might want to check with Clay Smith. They do make a smallblock pump, but it wouldn't fit on my engine. Might have something for big blocks.

What type of fuel feed do you need?
GPH amount?
PSI amount?

yes dyno at 702HP with still more in it. mild tune
1050 carb

I seem to remember the rule is 1/2 pound per horsepower per hour. So that would be 700 x .5 =350 pounds. At 6 pounds per gallonUS that would be 58 gallons per hour. Add a tad for reserve; say 10%, and that comes to about 64gph.
Does that sound right?

Well 64gph is about 64/(60x60) x 140 =2.49 ounces per second.
As a streeter, you could probably get by with a lot less, cuz where you gonna floor that beast for more than 6 seconds atta time? Shoot, she won't even be working hard 'til the 4th second!
In 6 seconds at full power,she could burn 2.49 x 6 =14.94 ounces
But you won't be at full power for the entire 6 seconds will you? No you likely won't be at full power for more than a couple of seconds.Unless you have some serious traction, and a high stall.Then maybe three or possibly as much as four seconds. So four seconds at full power and 2 at say 50% power that might total to 12.5 ounces. You wanna guess how much fuel fits in a pair of those 1050 bowls?
Doing the math on 12.5 ounces per 6 seconds, brings the gph down to 53.6
Please do the math for yourself.
6 seconds will put you deep into speeding territory.
If you run a bypass regulator, this math won't work.

To be honest the thing that I remember is a gallon of gas in like 15 to 17 seconds. This why I am asking recommendations. I just do not want to here the pump. Maybe the one in the tank, tanks inc I will look into this.
