Hey THANKS ya'll ! That's some REAL good info. !
I never even considered that NHRA would allow these crazy cams and spring pressures just because it would make teching easier. With all the tales I've heard about teardowns, I just assumed that they wanted to check everything they could on the winners and national record cars.
I figured that by now they had every kind of measuring and checking device and procedure that could possibly be needed to check every minute detail of an engine, at the track. And, as mentioned, the spring pressures would be easy to check.
Maybe they think that by doing less checking and measuring, they will make fewer guys mad, and keep 'em coming back to race. I can see where detailed teardowns, requiring precise measurements, would definitely keep most guys away from Stocker racing. With that in mind, they may start doing fewer and less detailed teardowns, as time goes on, just to keep the car count up. Ya think ?
It may evolve into a sort of "stock appearing" class.
