Geno was about 3350-3400lbs with him in it and launched @ 20psi to achieve a 9 second timeslip. You would really have to put the car (and possibly yourself) on a diet to get a 9 second timeslip out of a stock block. The TA block will be the way to go. Kinda costly but at least it wil be made to take the punishment of over 700+ HP.
