With so many changes next year here’s the NHRA race schedule.

In pro stock they are generic engines. They aren’t Chevy, ford, or Mopar. The day of walking into your dealer to buy pro stock parts are long gone. I follow drivers in pro stock and usually fast forward till the last two rounds if my driver is still in.
Back when Allen Johnson and a few others were running pro stock, they were running hemi's, and their torque range is higher than the chevy engines, so setting the torque limit at 10,000 rpms took away the advantage the hemi has above 10,000. At least as I understand it.
