Lacking mid-range power

Engine is a 70 LT-1 Chev. New Dart Platinum Eagle Heads - 2.05/l.60, 215 runners, Weiand Stealth Manifold, Holley 3310, 750 carb. Headman Ceramic coated headers, 2 1/4" stainless exhaust, 340 1962 Corvette Dist. Car is a '62 Corvette. Car runs and starts fine. Everything in Ignition is new - coil, wires, plugs, points, cond, cap, rotor. Engine runs smoothly and plenty of power if you easily give gas. If you hit the gas hard, it accelerates strong up to about, 3,500 rpm then seems to be somewhat flat until it gets to about 5,000 rpm (car will pull near 7g no problem). If car is parked and engine running if you crank the throttle hard it responds very quickly with no lag or bog. Fuel pressure is steady between 7 to 8 lbs. Any ideas why it might seem flat at mid-range?

in my opinion, the ports are on the big side for a 350 so it likely would seem soggy in my mid range until it winds up. Even so it is a corvette, I would throw the points in the trash where they belong and get a conversion unit.
