Preston, If the flathead 6 is anything like a ford flathead v8 they love turbos it's the best way to increase the HP&TQ of an engine. It,s easy on parts compared to any other way to increase power. You will have to fab a lot of parts, but keep it simple and you will have a successful upgrade. First question is what the use of the car will be, then how much HP can you use for this application?
