Thanks everybody for all the info on flatty 6 Ford.Learned where to find correct numbers in the castings.This tractor was apparently built from a Funk Conversion Dealer kit supplied by the Funk factory to a Ford dealer or possibly an individual shop.It has a 2N rear half,with a Sherman high range trans,Funk bellhousing adapter and clutch and the Funk 9 inch extended front end.I think the engine is an "H" model as the distrbutor is located in the left center of the block,haven't checked casting numbers yet.Engine runs strong when it runs,but has wrong carb on it,exhaust man cracked.Any help with info very much appreciated.
