I bought a nice solid 1939 Ford Convertible this weekend. It was supposed to be a quick flip. Well, I got impatient when buying (from a known seller) and didn’t test drive it. Got it home and took it for a short ride, zero oil pressure and a rod knock when warm. So, I need to change out the engine. I’ve got a good 327 Chevy and have a lead on a good running 8BA Flathead. Purely in the sense of resale value, should I put the 327 in it or stick with a Flathead? Assuming the cost to do either is the same, actually I think the Flathead will cost more.
