It's not exactly Ohio, but I recommend Dennis Piranio of Piranio Antique Automotive in Denton, Texas. Excellent babbit and machine work. If you are planning on a touring engine, I suggest you talk to him or look at his website. For me he rebabitted and line bored the block, counterbalanced the crank, machined 35 lbs off the flywheel for Ford V8 clutch, bigger valves, higher lift cam, high compression head. He did all of the machine work and I assembled the engine, but he will do it all if you want. Very meticulous and knowledgeable. And by the way, he recently set the land speed record at the El Mirage dry lakes beds at 150 MPH for a Model A Coupe!
