Caltracs and street

A few yrs ago I put CE slide-a-link(Comp Engineerings answer to Caltracs)on my 73 Dart sport with 4 speed.My car launched better,but nowhere near as good with an auto.I now just put the Caltracs in my 66 Dart,waiting on the mono,s.I also have the QA-1 12 way adj.My best 60ft with just stock suspension was 1.50,so hoping for 1.4?,s
