[F500] F5/FMod updates

Oh Dave, forgot to mention. The possible combination of a SWB and a 500 @
775# has been legal in Solo II since the 500s were legal in the class. A few
are already running. The MAC attempted once before to reduce the possible
WB/engine/weight combinations down a few years ago but the membership shot
that down. The Solo II class has multiple possibilities to determine the
correct weight for a given car.

An AMW 500 in a SWB @775# is nothing new. Scott and the Vees have faced that
possibility long before now so I doubt it is of any more concern to them now
then it has been in the past.
