Get the Strange Engineering 10 ways and dial it in yourself. Start at setting 10 and work your way down to see what works the best for you. Did you get some better drag tires yet. When you do get it to hook your gonna start to break stuff so be prepared. Here's a short list of weak points rear axles, get some 31 spline ones(Moser, Strange, Yukon), differential (Auburn, Eaton, Detroit Locker, FRPP), then you may also want to reinforce your torque boxes and get some good upper and lower control arms prefereably adjustable. if you spend some cash on it I don't see why you can't run 1.6 60' on drag radials and still be streetable. What psi are you running in the back tires. Usually between 15-20 psi works the best.
