i run a rpm air gap on my 347. i use a trick flow stage 3 camshaft with 1.7 rockers, 850 demon carb. i go through the traps right at 6500 rpm and car is still pulling. the rpm range of my cam is 2600 -6100 power range and i have a 3800 stall converter.

I have an RPM manifold on mine and it will go to 7,000 no problem. On the dyno though it peaks at about 6,400 without nitrous. On the juice it makes peak at about 6,600. I would like to try a victor jr to see what that would do. I think for a street car the RPM is a great manifold.
