checked the rules that are posted (2007) don't see why they would change.

i would like to run at Fayetteville this year but my engines are dry sump, but the engine itself goes by the engine rule. When I race there in 2002 they had the same engine rules but you were allowed to run dry sump (and weight was 2350). Allowing dry sumps and a lighter weight may be something to look into
