Your launch is great, but it seems to me that your MPH is off. That means you are low on horsepower. I would start withthe basics. Disconnect and plug the vaccum advance hose and then check the timing at maximum centrifical advance. You can do this by putting a timing tape on the damper, or using a dial back timing light. Watch the timing mark while revving the motor. The faster you rev it, the more it will advance untill it reaches its limit. Set the timing so it maxes out at 38 degrees. Don't worry about the initial timing yet. Your total timing is what matters.
Also make sure that both your primary and secondary throttle blades are opening fully. Whith the engine off, look down the carb with a flashlight while some one floors the pedal. Adjust the lingage if needed. If you have mechanical secondary carb, you can check the primarys and secondarys both this way. If you have a Quadrajet, check the secondary air valve to make sure it isn't stuck or binding, plus look at the throttle blades. You also need to make sure you are getting enuff fuel to the carb at the big end of the track. You can rig a fuel pressure gauge temporary. Then go thru the gears and make sure pressure isn't falling off at the big end of the track.
Try these easy tricks and see how it does. I think your car should go at least 100 mph, if not 105. GOod luck! [img]/ubbthreads/images/graemlins/burnout.gif[/img]
