I have magneto that I think is for a ford 6. The reason is it is hex key drive with a gear that ain`t even close to a chev. I know nothing about fords and can`t post a picture.It has about 20 degrees centrifugal advance and when mocked up on the bench, throws plenty of spark on all six plugs. I`d like to see it used by someone.
The flathead Ford six distributor ('48 and later w/ side mount distributor) has a .459" diameter 14 tooth gear that is integral to the distributor shaft.
