Love this car. Bill are you aware that there are 2 completely different versions of Ardun heads in the Revell '50 Ford p/u ? The first version had a very short production run i think because they were noticeably undersized and oddly shaped .I've never really compared them to pictures of the 'baby' Arduns or mocked them up on the V8-60 block but they might be a good starting point for a V8-60 conversion. Just thinkin' a little outside the box. Tim Boyd would probably be the guy to ask regarding the earlier version Arduns in the first run of the '50 Ford p/u.
