Caltracs question

Thanks for all the input guys ... yes, car weighs 3311. I've used the wallace calculator and that's what is frustrating! What should a good range of 60' be over 6 runs? 1-2 hundreths???? Less???

I am thinking I'm pushing the limits of my tires (10 yr old M/T drag radials) and my Auburn diff .... spool and new tires for spring and see how 60' responds

I found 7 old et slips from 1990 from my big tyre (Hoosiers) '69 440 Cuda....11.0's with current set up at the time, 60's were>
1x1.62 at a T&T
3x1.58's race meet
1x1.56 race meet
2x1.55's race meet
all at Santa Pod, all a bit off from the 1.54's or better that they should've been, the car didn't leave hard with 4.5psi we ran in them days in that size tyre.
