I gotta a picture of it, John, and I'll see if it's got any spark plug wires... I'm kinda sure I would have noticed if it had no ignition system but I'll go back and look at the pics...
The GM 350 diesels, BTW, were junk for many years... Bad everything... Rosa Master injection pumps were good for about 25K miles and done... Heads leaked and cracked so GM put more bolts on 'um... Then the cranks gave out...Junk... I don't know why GM didn't just buy dependable IH engines??? I mean, they uses Isuzu diesels in some of the Chevettes...
