something is wrong!?

i would leave the gear, im wondering about your timming curve, and is that a 4500 series 1050? your car should run in the 120 mph range from watching my buds 416, 4.30 geared 28 in tall 3000 lb cuda, it runs 10.8os 120-123 mph. thats with a 750 witch i dont think is big enough.
