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
