I vote cal-tracs. My 69 dart with an indy headed 446 and a 250 shot went 5.70's in the 1/8 on a 10.5w and cal-tracs. And it did not matter what track I was at the car worked. After you get them set it is easy to adjust..
There are some real fast cars out there on stock style suspensions. I for one do not care nor do I want any car with SS springs... Makes the car look like it is a 4X4..... Not to my taste at all.
