You absolutely have to have traction bars for a good 60 foot time with leaf springs! I have heard that Infineon Raceway is an excellent track. I would definitely stay away from slicks. On a frameless first gen the rule is 'Wrinkle Walls = Wrinkled Quarters". I got into the low 12's in one of my 69's with BFG drag radials and traction bars. OK, ok, I used Nitrous!
