fastest stock suspension 2wd cummins

bolting my s400 on thursday and hope to go to the track sunday and see how bad she spins at the track with 1500 spings in the rear an no overload springs.
 
I know Addictd ran a 10.25 with leaf springs in the rear and no four link. Its too bad he blew up half of his intake piping at 2/3 track, may have gotten into the 9's.
