The 9N L-Head is probably a better engine and as Gaspump stated, not a lot of similarities. The early V8 came after the Model A and the 9N engine was based on the 85 hp Mercury V8 cut in half. If you are thinking of swapping out 9N parts with Model A parts, forget it, it ain't gonna work. Parts are unique to a vehicle based on the prefix code. "9N' signifies the 9N tractor or thereafter. Look through parts manuals and you will see a lot of parts with "01A" or "59C" or B-xxxx, or several other part markings. These mean they are used on other vehicles as well. 01A is a good example. the zero designates first year used, in this case 1940. You see a lot of fasteners and hardware common to all passenger cars, trucks, and tractors. Other than that, you won't get say a 9N10000-B generator to swap out with a Model A one.
