Butttttt NHRA has already signaled on this one.

Ya that’s what I kind of figured. But that’s a lot of different combos to figure out how many hp they get hit with for switching to a roller. Then do they make everyone change or have 2 factors flat &roller. We know NHRA is trying to cut labor costs. Look at tech. My bet is it’s a combination of the complaints that will follow and labor costs. Are what’s stopping them more than letting stock slip away a little more.
