so i am going to be buying a new manifold but i am stuck. i am either looking at the rpm air gap or the victor jr. i heard both work well but which one. I currently have the original rpm manifold on my car. what is the difference in the ports between the original rpm and the airgap or are they the same? what will work best with my combo.

-331 stroker
-TFS high port heads
-750 pro form carb(soon to be bought)
-XE282HR-12 comp cam
----232 int./240 exh @ 050, 0.565 int./0.574 exh. lift, range 2,600-6,500
-9.5:1 compression
-stock 5 speed

WTF is a Vistor jr??? jk I say RPM Air gap so you can keep some of that low end torque and still make power at 6500. It is a street car after all.

EDIT: I believe the ports are the same on both RPM's but the air gap's are probably a bit longer, and the air gap has a dual/single plane kinda design (kinda) because of the height to it and the cut in the divided section at the carb flange.
See what I mean?

here are some actual test that were done on both. the motor has about the same specs as me. they did dyno test with both and both are about the same. just peak torque number are at different rpm ranges. there are 3 pages check it out sean. oo and yeah i did suspension lol i will get some pics together for you and send them to you. sorry i forgot i was to damn busy with gay school

Maybe for high end 6500+rpm HP. But not for a DD street car that needs mid range torque.

Here is your answer right here Kyle.
The question on the table now is, which is more useful, an extra 20-25 lb-ft through most of the mid range or the slight advantage in high-rpm power? For this particular mild application, the dual-plane would be much better suited for street (and occasional track) use. Ideally, the single-plane intake would be combined with more of everything, more compression, displacement, and even wilder cam timing to maximize power production higher in the rev range.

or the Wiend Team-G is good single plane as well..

lol yeah that is basically what i am gonna go off of i think. the only thing is superman is gonna sell me his vistor jr for a good price cause i just took his nice 750 off of his hands. ahhh lol also i was talking to frank(superman) and he said with my nitrous plate the rpm air gap would be horrible. since it is duel plane the higher side will get all of the nitrous and could blow one side of motor. but also i was thinking screw it i will just get fogger system:lol:

there is no weiand team g for 302 ford i believe. have you tried both manifolds?

yeah bro i beleive you can. its a pretty bad ass set up i would like to do if i could find a cheap F.A.S.T system. and also for sure do it if i could induction

For what it's worth, I wouldn't spray anything with a dual plane on it, If you feel the Vic.JR has too much cross section for your RPM curve, you might rethink the Torquer II, not the greatest manifold out there but with a 1" carb spacer and the plate, it'll have plenty of mid range when you're not on the button...just a thought.

thats the reason why i went with the tqII and not the vic jr
