Is it possible to get the bog out of a two four high rise manifold, to make it street drivable, or do I give it to Waste Management?:confused:

maybe, depending on cam, and carb size as the rest of your combo. to make it more responsive you could go with dual 390 holley`s, a open plane intake is drawing off the entire mass under the carb, so fewer total cfm is acceptable. as i said, depending on the rest of the combo will dictate the rest.

I would go with vacuum secondaries also. Sorry if 390's only come in vacuums, I've never seen one...

It's on a 454, cam is 286 intake, 296 exhaust. I think it would be considered a 3/4, MSD ignition, rest is mostly stock, 450 Hollys.

isnt that a bit much on the duration? most of those kinda cams are for 2000 -6500 apps i thought?
that's where i would look.

This is what was in when I got it. Where should I be?

I'm not a cam afficionado or any cam guy. However for a street app. most don't go past 280 to maintain streetability. After all your not running at full throttle all the time. comp cams makes a pretty good listing of different styles of cam. even switching to one of those 280's would probly help you out.
That is of course provided you have eliminated all of the obvious first (carb, timing, fuel filter, wires, plugs, etc.).
My two cents
