Thats what everyone does around by us. Well they try to do it. if your serious you need a trustworthy tach for stock RPM's and a dyno for horsepower. Find something like the old M&W sheets to go by. They had RPM and horse on them, at least the set Ive seen did. Now you can either dyno everyone or dyno the top 3 or dont dyno until someone b!tches about that 310 in a 77. There is one place that dynos everyone be fore the pull around here. Lets not forget the stock hitches and stock weights that everyone must have. What about class jumping? Around here we have guys go from stock to modified all the time. Not everyone likes that. I say you either build to run with them or dont pull. i think if you start a stock class your just going to open a whole new can of worms and its going to turn into a soap opera, least that's what ours has become.

I response to your dyno idea. If you go by the Neb. test for a DC Case which was only tested in 1939 at 37hp with 3 7/8 pistons and a 4570 head and I come with a 52 DC with with 4" factory overbores and the 5505 gas head and it dyno's 45hp am I in violation of the rules? I think a dyno check is about as big of a waste of time as I have ever seen.

Well it depends. At the pull where they dyno everyone you would be put into the 5000# class automatically. They run it 30 horse = 3000# - 40 horse = 4000# and so on and so forth. At the other pull where they might only dyno first place, or unless someone b!tches about someone, a 45 hp DC probably wont take top place so you would be fine there too!
