Offy (Offenhauser) bellhousing to mate a Ford toploader to Chevrolet engine. The toploader was deemed to be stronger back in the day. This is NOS never used, 60's era, very rare. This will fit any standard bolt pattern Chevrolet small block or big block. $200 complete. Would consider interesting trades.
