Both Shafiroff (http://www.shafiroff.com/) and Bill Mitchell (http://www.worldcastings.com/) offer top-quality crate engines in the displacement range you seek. Our advice is to visit the Web sites, speak with representatives of both companies, and decide what package best suits your budget and intended usage.

Good luck.
