Look at the Little M Sportsman block, the material and finish machine work are superior to the World blocks. Ohio Cranks have had a poor rep on several forums I frequent. For a budget build Eagle and Scat are good choices, although Callies quality and finish work is worth the extra if you can handle it. Look for a good local builder to put it together, Ed Wilson/Edvanced Engines is a moderator on several forums and is in your area. It might cost more now, but if it fails as many have had with Ohio, what will it cost later?
