I am with you guys on this one. The current valve spring rule was the most expensive hit NHRA has done to Stock Eliminator racers. I agree with you, Terry, that if they would set a max of say 135-140lbs on the seat and 350 or so at .500" compression the cost of an engine would decrease, the reliability and down-time would increase and the smart guys would have another avenue to snooker people with.

If someone would start a referendum, maybe we could exert some pressure on them. Lots of people would benefit.
