Last year at the Classics it ran a best of 13.26 @ 103 with a stock converter and 215/70/14 rear tires. 60 ft times were 2.0s at best. This year it has a tight 10" converter and 275/50/15 M/T drag radials. With that cam and converter combo and hooking up hard, what kind of gains do you think I could expect at the Classics in a couple of weeks? Not looking for exact, this is just for fun. 13.10s? 13.00? 12.9?

What do you think?

Thanks
