I recently acquired a GM (Pontiac) 200ci flathead inline six out of a 26 to early 30s car or truck. The donor vehicle is pretty well gone but the engine is salvageable. It had been sitting in a field for 50-odd years and there seems to be a lack of parts for this thing. Any tips on building this thing since this is my first flathead and where I can find parts would be greatly appreciated. Also, where I could find any books, especially wiring diagrams, or other literature would be helpful. Thanks
