Can I hit the 11's? low 12's

Went out to T&T for the first time, I am a total newbie to racing, so figured I would test out the 71 Dart I have been working on. Here is the information on the car. 71 Dart Factory weight, bench front and rear, belts, 440 with 2800 convertor. Motor was dynoed at 425, with all shops hi end HP stuff. I put on a V/S 750, smaller schumacher headers, 2 1/2 exhaust, P/S, water pump, 7 blade fan, has 5/16 factory /6 fuel system, mechanical factory fuel pump, no frame supports, battery in trunk AND track is at 4,000 feet (some say true DA alt is 6,000). Rear end is 8 3/4 with spool and 4:30's, tires are 295/65/15 (big) coming through the traps at 5,200: Tire pressure 30 lbs, Here are results, last run, only change I made was adding a bit of timing.

R/T0.5760.6260.4960.4340.595601.8831.8781.8871.9042.1033305.5595.5265.5535.5325.7391/8'8.6358.6028.638.5748.743MHP79.7279.4479.7480.3482.03100011.29711.27311.29511.21911.3311/4'13.55213.54213.55713.45113.518MPH100.0499.2199.7100.98102.88

So - now I am itching to get back out: What I have done since this is a 1/2 fuel line with 3/8 return, Walbor pump (Had to fix for tech, had too much rubber hose, and issue on top end, was falling down a bit to starvation) Full US CarTool frame connectors, a sump (guy welded it on backwards, but have to use it, no cash to fix at this time) A battery disconnect and Holley 750 Ultra HP DP. Goal is for the high 11's, Low 12's. Any thoughts, suggestions, insider tips, speculations on next times?
