I know that when SOD announced this open engine rule before the 2016 season, there were a number of naysayers. Since they're sticking with it this year I presume it was fairly successful. How were the car counts? I'm guessing if most of the tracks were dry/slick that the 410's didn't have a big advantage. Was that the case? Or with the tire limits did track conditions really not matter that much?. I'm just curious. Thanks!
