Pinto drag car gets loose down track
 
Ok guys, we have been working on a 73 Pinto tube chassis car, ladder bar suspension, Strange coil overs w? 110# springs, Strange struts up front w/ 225# springs. 2400# with driver, 650hp 406sbc with a powerglide, 14x32 slicks. We have been battling this car to get it to launch and stay straight down the track. We finally got the launching part ironed out somewhat with a 1.29 60' tonight, but now the car skates around from 330'- the 1/8th mile, peddling it several time he ran a 6.36, then the next pass, he ran a 6.09 still having to feather it most of the way. Has anyone had any problems like this? Or any suggestions on where to start looking?

Thanks guys

I'm thinkin' maybe your rear coils aren't rated high enough. Maybe some info in this link that might help.

What pressure are you running in the rear tires do you have a video of the car going down so we can see how it is acting

7 psi in the rear, and as far as springs, they are actually the ones The guy at Strange recommended for the car. As far as a video, I don't have one. One of the other guys may, I'll ask the owner tomorrow.
