yes sir, 2014 rule book has no mention of E85 (perhaps because of the alcohol content?) , but talk around these forums says that puts me in the fuel class. I'm just trying to figure out which fuel class.
unblown fuel altered maybe?

I could be wrong, but depending on the displacement of the LSX engine, you would probably run in one of the following Fuel Coupe classes: AA/FC, A/FC, B/FC, or C/FC. The engine swap knocks you out of Production and puts you into the Coupe class (which is a level within the Modified category), but you need more modifications (e.g., a step pan, a large engine setback, or covered headlights and grille) to move into Altered. The use of E85 knocks you out of gas and into fuel. So you're basically a Gas Coupe that's not using gasoline, which makes you a Fuel Coupe...
