Single Fed 4 Barrel

[clark]

I have been running a Holley 700 double pump all year, but need to put on a single fed 4 barrel on for a big race in 3 weeks. "NO dual-line, rear metering block, or double-pump carburetor".

What carb should I be looking for here to replace my current one?

I'm no carb guru and have never claimed to be so any help here would be appreciated.

Thanks,
Clark

years ago, we ran a class like this, we ran a 750 holley vacuum secondary that had no metering block on secondary, we replaced the duel line bowls with ones from a 600 that has only one line going to carb and a tube connecting the two, also best I can remember we used a purple spring in the vacuum secondary , this let the secondary open quicker, I cant remember every thing we did, but it worked well
