My 360 setup is 4.10 with a 28, 2830 lbs on the line, SLR = 11.23. Hooks with 1.48-1.52 60’…hook ratio is 1310-1320. Not sure how heavy you are, maybe the jump from 10.5 to 11.78 will be okay? May just need some suspension and launch rpm adjustment.
3350 at the line, I footbrake,car mostly is 1.48 to 1.50 60 foot, has been 10.68 so far.
Do think front shocks needed tightened up( too much separation) and needs more flash regards convertor.
