I was wondering if you guys new any good single plane manifolds that would work good on my car. It is a 3000 pound car, has a 350 in it with a holley 750 dbl pumper, I race on a 1/4 mile track and minnimum rpm is 3000 max is 5800 (comes off the corner around 3,200 rpm). I have found a few in the rpm range I need but they dont have the 4 corner water outlets that I need. Any info is apriciated!

If I were you, I'd run a Performer RPM AirGap. You're well below the RPM range of a Victor class manifold. A Victor Jr and/or Super Victor were designed for 3500-8000 RPM operation. The RPM series was designed for 1500-6500 RPM which is a much closer match for your application.

A Victor would work to kill tire spin off the corners. It'll be pretty lame until 4000 or so.

What cam are you running? Hopefully around 240@.050" or so. Exhaust - headers or manifolds? It's more about matching the entire system than just stuffing a manifold on with 4 port cooling.

it has a set of headers on it with a set of purple hornies for mufflers. The cam is a crane saturday night special I think duration is around 230-235 @.050 it is lifting .484 intake .490 exhaust rpm rang is 2200-6200. the heads are 291 camel back castings with .194 intake .160 exhaust. it has a stock bottom end.well thats all the info I can think you might need if there anything I forgot let me know.

Definitely the RPM Air Gap. And it has 4 port cooling too.

On a dyno I saw a victor jr out torque a dual plane, a Edlbrock RPM and a BOW TIE. This with a solid cam and on a later test with a hyd cam. When we tried porting the intakes the Jr started to move up in the rpm range and the RPM passed on the bottom end but only after a lot of port work. I believe one of the mags had the same results about 1 year after we found out.

I agree with raz. You have to consider your cam and gear ratio. A victor jr can out torque an air gap if the right combo with the heads and cam. That 750 carb could also be too big . It's all about the entire package.
