Default launch question

I finally finished porting the heads, again and gained about 25 cfm at .500 lift. Although the car is not real fast, it is a fun street car that I race in the Sportsman class. 12.00 seconds is as quick as you can go.

I could feel something was not right and did not know if it was the tires or the carb, but the video, link below, shows the up, down, up of the front end. Also is an attached photo of my homemade 4 bar.

The front suspension is all newer factory/stock components, shocks, springs. etc. The front sway bar is attached and the rear has no bar. The battery is on the pass side in the trunk. I do have air bags, but must have blown something on Saturday's racing so on Sunday the passenger side air bag did not inflate. I have adjustable rear shocks.

Sunday morning time trials, the 60 ft was 1.67. Early evening 4th and 5th elimination rounds the 60 ft was 1.71. The video was the 4th round.

The instant center of the 4 bar is 39" forward and 1" below the frame of the car. I could set it at 59" forward and 1" below. Would this help with the launch?

Thanks for your help, Tom
