rebuilt chevy 350 help

I have a 350 chevy that I did a top end job on. It's a 1976 4bolt, stock pistons and crank (in excellent shape). I put it in my 66 chevelle and have been working on it but it runs like crap when I push it (bogs when I hit the gas hard and after it finally picks up, it loses pull at higher rpms). I am getting nowhere near the performance I should be getting.

Heres whats in it:
- completely rebuilt heads - 60cc, 2.02 intake, 1.60 exhaust.
- comp cam xtreme energy 274 cam, .490 lift intake and exhaust, tappet
lift 274
- new comp cam hydraulic lifters
- edelbrock performer manifold
- edelbrock 750 cfm 4 barrel carb
- on the rebuild, new, high performance oil pump, fuel pump (mech), water
pump, radiator, gaskets,seals , etc.
- rebuilt saginaw 4 speed trans
- new points distributor, and high energy coil

dwell is set at 30 degrees and timing is set at 4 degree BTDC

Despite all this - it runs like crap - HELP!

Timeing should be 10-12 degrees before TDC.

You'll run out of camshaft way before you run out of carburetor. A 600 would have done it. Anyway, try to tune it for the motor as best you can.....
