Viking 9 way adj shocks on rear stock shocks up front.......I was told by a few ppl not to use calverts with SS springs........I had them so I put them on......adjusted them till the play is taken out, no preload at all......1.45 60 foot with front wheels off the ground a couple of inches..........goes nice and straight as an arrow....haven't tried anything cause pretty happy how it is.........fastest time so far was Saturday 10.37 @ 129.65 mph with a 1.45 60 ft.........kim.....oh ya 470 stroker detuned till the daughter gets used to it........
