I was a NHRA tech inspector for 6 years. A lot of the rules in the book don't make sense to some people because their car doesn't have that particular problem. All of the rules in the book has someones blood on it. I don't think I should have to buy a aftermarket balancer for my 10 sec. 440 because the stock one has a lip that makes it impossible for the outer ring to run off, but a high winding 283 Chevy will throw one off in a second. I have never see fluid come out of the top of a 727 dipstick either, but their others that will do it. The 10 sec. Chevy guys that run Powerglides are probably mad because they have to run a tranny shield because 727's are so prone to blow up. The rules are hard to understand sometimes and costly, but they have to be fair to all. Now the 2 year seat belt rule is another story in my opinion, but I won't go there.
