Evaluate this 383ci combo

New nodular cast 383 crank
Speed-Pro Hyper. flat top pistons
4340 I-beam 5.7 rods full floating pin ends
Sealed Power moly rings
Dart Iron eagle heads, 64cc chambers, 200cc runners, strt. plugs
3970010 '72 350 4-bolt block
Holley 600 double pumper vac. secondaries
Hooker Comp. headers
Felpro gaskets

According to Scoggin Dickey catalog, should have about 10.3 CR.
I'm open to suggestions on the intake and camshaft, and any and all suggestions are welcome. I'm hoping to make good low and mid rpm torque with this motor in the '72 GMC. Oh, and as for a camshaft I'd like to keep some vacuum, but want a little lope for "effect". Anyone tried the new Nostalgia Plus cams from Comp? Thanks
