i talked to hastings rep the other day, they sound like they have pretty good plasma moly ring set for the 107s. they said there is an 80$ diff in the set w/cast top ring, and the set w/ductile top ring...(i.e. street vs race)

In a conversation with a Wyoming State Patrolman... "A 318 ??!!! But I clocked you at 142 mph!!!"
