Stop in for a cup of coffee

Heres a good one doing two Marine prestollite distributors for a guys boat, just about the same as a reguar one and I have the books on them. Noticed both reluctors are set for B/RB enginges these are 318's. Have a call in to see if they were running funky for him, pretty sure some one was in these before.
Counter rotating engine? That would explain that.
