1952-59 Ford Holley 94 questions...

I'm running two Holley 94's on my 'yard art' rod on a dual clifford manifold on a Ford 300 six with a stock point distributor.

Do I need to pull vacuum advance from both carbs or one to the distrubutor?

What fuel pressure should I set with the fuel regulator?

 

Just one. The vacuum will be relatively consistent and no "average" is required. Be sure to check your vacuum advance unit for proper operation - no leaks and no untoward friction.

I'd run 2 to 3 lbs. fuel pressure. These carbs can probably withstand more, but I doubt that you'll need more. Keep an eye on the plugs and re-jet the carbs as necessary to keep 'em a nice mid-tone gray/tan color. Sooty = too rich.

I'd run a mechanical choke on both carbs, but hook up to only one. This should give you enough mixture enhancement to start the engine and is much easier to hook up than two chokes. Close the choke as early as possible to avoid fouling the plugs. It's gonna want to run rich all by itself.

Use a Uni-Syn to balance the carbs on idle. I think I'd toy with the idea of making one carb open just after the other in order to minimize off-idle bog if you're running a low-stall automatic. You'll also need a couple of those little vacuum-operated throttle-close retarders (can't think of what they're called) if your running an automatic. Came stock on all Ford Ford-o-matic cars and are easy to come by.

Hope this helps. Good luck!

 

Thanks Eric for the help. I'm running a 3 speed manual and did get the chokes hooked up and set perfectly. I also have an electric fuel pump and a Holley fuel regulator that's adjustable from 1 to 5 pounds and a liquid filled pressure guage to see what I'm running for pressure. I've got a few new pics on my album page. I'm waiting for the fuel tank and basic wiring, then I'll start it up. Brakes, throttle, clutch, choke, and almost fuel system are all ready.

I have a Uni-syn already, it worked great that last time I used it. The carbs have been rebuilt with all the good stuff and were flow tested and wet flowed to match the 300 six's air flow at idle and at speed. They were also fitted with the adjustable main jets so jetting should be a snap.
