my old hemi car went 10.40 w/ 002-003 super stock springs. they moved the B body rear- forward because the front of A body springs are shorter. too bad we didn`t have decent tires back then! I have a cal trac set up on my 68 barracuda, and a set of 002-003 springs w/ imperial shocks. not sure which I`ll end up running. the caltracs seem to ride rough so far./
