A non local friend of mine has a straight six engine he's not sure is it is a 200 or a 250? He's asked me to help him i.d. it.I can usually spot the differences, unfortunately photos of the engine are not an option at this point.Does anyone happen to know casting numbers? According to my friend it has D8BE-6015-JA .Cast into the side of the block I know D8 = 1978 and 6015 is Ford's basic engine number.Any help would be greatly appreciated .Thanks
