Combo: '72 Dart, 451, .652 gross lift (272@.050) cam, QFT 950. For now, running bowl-blended iron heads. Will shortly be putting on PRH-massaged Speedmaster aluminum heads good for 293.5 cfm, 10.6:1. A833, 3.91 rear (3000 rpm @ 60 mph), caltracs, dual 3" exhaust with x-pipe. And a 100-150 hp nitrous plate if I feel the need.
Most of my thoughts have already been posted by others, but FWIW.
That is a lot of cam, especially for only 10.6 CR.
Where does the current combo like to be shifted at the track?
I would have the Speedmaster heads milled to up your CR, hopefully 11.0-11.5
For the cam and nitrous I give the nod for the Holley SD and as much spacer as you can fit (since the Edelbrock is taller already).
I think that new combo will go to 6500 rpm easy. But both intakes should be good.
