I agree with Brad, first off stop the thing from rolling...

You forgot to tell them you did that with the back tires. Lol

Chassis looks to stiff. Does not seem to plant the back tires. I would guess something is in a bind in your rear suspension. You have plenty of power. With the short times you have posted mid 1.20 60 Ft times should not be a problem. Check all of your angles on the ladder bars and pinion angle. Loosen the rear shocks and let the suspension work. Is that a mono leaf spring?
