Is this a good street setup for hauling butt? (new info)

1970 Dart with stockish suspension... Its a 383, 727, 8 3/4, 742 suregrip, 323 gears in rear atm, and I have 2800 stall, and 27 diameter rear tires, 255's... Also, Shumacher headers...
With 750 edelbrock carb, Street dominator holly aluminum intake, stealth aluminum heads (just looked over and squared), light weight anything possible (aluminum radiator and water pump housing, etc), Comp Cam 274 extreme energy (4.9 lift/hydraulic), 9.1 - 9.3 compression (current estimation), stock gaskets, etc...

So, this is a pretty good setup? We have it all mostly together, was just wondering what smallish tweaks or changes we might do that would create a noticeable benefit...

Or even what things u might change in the future for when this car gets gone all through again?
