my van weighs 4450 lbs with driver, makes 340 whp N/A, and runs a best of 13.70 @ 99.8 mph with only a 1.9 - 2.0 60' time (my converter needs to be swapped!). I run Eddy heads (box stock other that minor clean up of machined corners and machining the push rod holes out to clear the angle of the roller cam/pushrods in my old LA engine, which shouldn't be a problem in a magnum engine. My cam is the crane retrofit #4 cam, 112 lsa, 107 installed intake c'line, 230/238 @ .050, .528/.548 lift, an edelbrock RPM airgap intake and Holley 750 VS carb. Headers, etc. for everything else, so the potential is definitely there to make 400 hp without too much work. Oh, i have 10.2:1 compression also. It operates my power brakes fine on the street too Not sure what my vacuum @ idle is off the top of my head tho.

Good luck!
