Edelbrock with stock fuel pump?

[Pesty351]

I decided to keep my 84 tudor and I finally have the money to beef it up a bit. My ? is with a total edelbrock top end kit(heads, cam, intake, carb.) will a stock 84 fuel pump keep up with it? If not if I get a mechanical fuel pump would it be able to pull the fuel though the stock pump? Also what stall do you guys suggest I was thinking of some thing in the 2200-2600 range or would my stock one still work?

Well, if you have a typical 302 car, you're running CFI, which has a high pressure pump. Not compatible with the carb really. If you have a carb car, then the stock pump should be fine.

a full top end kit should put you over 300hp, not sure if the stock pump will keep up with that. and you dont have to go with a mechanical pump, they make a lot of electric fuel pumps for carbs

Get a Holley Red universal fuel pump PN 12-801-1 and be done with it

If you have a cfi car, you will have the eccentric on the cam gear to run a mechanical fuel pump. Your timing cover will need the fuel pump boss hogged out in order to use one. I would not leave a nice motor to be jepordized with running lean on a stock pump. A nice mechanical fuel pump is cheap insurance. Its tricky with the frame and the power steering pump, You need to clock the pump to make the lines fit. But it will make the lines go straight into the frame rail. So some tight bends need to be made without kinking the line. I worked ok when I had an old carter high performance fuel pump.


If you want to go electric. Which I would, cause its easier and theres no trying to prime the pump and all that hassle. Get the "Summit" brand fuel pump and regulator. Its same as the TFS pump for like $30 less. Its pretty noisy tho.

As far as the converter, I would either call edelbrock and see what they suggest or call and find out where your the peak torque occurs then go about 500rpm below that. Prolly will end up around 2200-2400rpm me thinks depending on what top end kit.

So If I go with a electric pump should I try to find one that will drop in the tank or a inline pump?

The holley pump is adequate for a stock or very mildly modified motor. The Holley blue pump mounted under the car is louder than my aeromotive in the trunk, even when i did not have a rear seat or firewall. My $160 Aeromotive pump will support 750HP with a carb and non-bypass regulator, with a bypass regulator it will support over 1000.

MagnaFuel is the top dog.

Holley blue pump PN# 12-802-1 95GPH @ 7PSI and 12v. Max HP 550. Non alcohol compatible.

Aeromotive Street/Strip P/N 11203 125GPH @ 7PSI and 12V max 1000HP Safe for use with alcohol. $170 From Summit

For $44 more you can get a quieter, better built pump that will support almost twice the power.

That amount of HP will require upgraded fuel lines also...

300hp

Carbs require 4 to 6psi to work properly.
TBI reqiures 9 to 11psi.
You will need a press. regulator near the carb set at 4psi for the carb to work right.
Or, remove the pump from the tank, replace it with a 3/8" pick up, and use only a mech. pump, or only an external electric pump.

The problem is the factory 5/16" fuel line will not move enuff volume to supply more than 300hp. Above that, you will need a larger line.

For a convertor, get a good quality lock up in the 2200 to 2400 range.

We are assuming here that the exhaust has already been changed to free flowing to get the most from those heads and cam.

[Pesty351]

All right Ill go pick up a new fuel pump, most likely to holley (best for budget and I don't mind the noise). As far as the fuel lines go how big do I need and do I need a pickup the replace the stock pump to or can I pump though it?

[torquelover]

Uh-oh. I'm running the stock lines in my car as well. Should I run some new lines?

[mrltd]

I doubt you are running over 300hp with e7's

[torquelover]

I doubt you are running over 300hp with e7's

Very true, especially with unported E7's. If I change out the heads, I imagine new lines might be in order.
