I would easily agree to addition fees for setting records or tear-downs to fund better administration in the tech department for Stock and Super Stock.

I totally agree with Dwight, and it would require a lot of the specs issued by the OEM to be realistic!!! If can recall correctly,I remember the Chrysler 440 and 340 cam specs having something like 240 degrees of overlap and unreal durations specs. The same applied for other makes.
