The $15,000 dollar engine is dry sumped...Dry sump is not allow in our series...of course you knew that but wanted to start crap anyway

Wayne, I have been asked by several people if I would build them a D-2 engine. I have turned them all down, partly because nobody seems to know what the rules are day by day. Now you claim dry sump engines are not legal with your D-2 series, but your own Gater Dirt Nationals flyer for 2018 says wet or dry sump is ok. Which is it? Do you tech cams? If so, what method and or tools do you use? What are the legal cam specs for each engine (including the motorcycle engines?) Do you consider any manufacturing and/or measuring tolerances when determining the legality of the cams? What is the maximum compression ratio for each engine (including motorcycle engines?)
