Have you checked Ohio crank? They make billet cranks with CCW for a decent price.
I called them recently to see if they would make me a billet 4.375 stroke hemi crank with full counterweights and BB Chevy rod journal size, the 1-800 phone guy said no, not in that stroke I'll call back later and talk to one of the owners or senior sales guys to get what I need
