XE274H cam sound like? Heads Choice? Help me decide on combo for chevy 400

Im having trouble choosing my cam...and heads. The engine is a chevy 400 which will be rebuilt - 9.5CR, 1 5/8 headers. The car (72 nova) will be driven everyday with some weekend track duty, with a TH350 trans with around 2500 stall and either 3.42 or probally 3.73 rear gear (is this overkill for daily driver?)

For top end it has to be either - ported 202 heads with weiand 8004 intake and qjet. Or vortec heads with air gap and 750 holley ???

For cam, its looking like I would like comps XE274H(from what Ive seen, this cam gives great power) Any other cam suggestions? Would this cam work good with the combos above? Is XE274 overkill for daily driver?

I would really love the car to sound like this - http://www.antechlabs.com/K0GFM/65Impala1.wmv That is a XE274H in a big block...with the xe274h in a small block 400, would it rumpity the same? or more?

Desktop dyno puts both combos with the XE274H at around 400HP@5000RPM and 430FTLBS@2000RPM with peak torque 455FTLBS@3500RPM -- My goal/ Id love to put 300 HP and ft lbs to the rear wheels...does this combo come even close? Considering Im at 4300 ft elevation? Do the DD numbers put me in that range?
