My go to has been Melling for years. Need more information on the application, since you mentioned the Shark Tooth pump I'm guessing SBC?
Street, drag, street and drag, track only, main and rod bearing clearance?
Melling stock replacement pumps aren't honed to size anymore in the pump gear cavity. That stopped around 2005 to save money. The Melling select lineup are great pumps for just about everything short of a full blown race application (outside of SBC and BBC applications where full blown billet race pumps are available).
Outside common domestic applications I'm sure there are niche pumps that are wonderful, but I don't work on that stuff so I can't make any recommendations.
