Anybody have a copy of the rule book that would be willing to let me know what the rules are for Super Stock Diesel class? Can't see buying the book for one pull.

Yes sir, try to get out that way every other year, looking at the Nationals in Bowling Green OH, 1 hour away from home :)

My truck currently meets NADM rules, just wondering if there was anything different with the NTPA rules that I need to be worried about, their using NTPA rules at the Bowling Green, OH hook in August, and I don't want to drive across country to find out I was missing something.

Thanks,

The clutch and bellhousing will have to be inspected for anyone to pull at an NTPA event. If you are not a member, it will cost you $50 for the inspection.
 
rules 3 and 4 dont make sense to me.

why is a v8 only required to have .060 al. side shields and not .125 steel or .250 al. like the inline engines do?
 
A rod coming out of a motor will be a whole lot more likely to go in the ground then the crowd.

Don't a lot guy's have triples in this class out that way?

^^^I believe they still use the tripple setups in a 2 stage system. 2 primary chargers feeding a single secondary charger.
