I found the head to be a 53-up. This explains the older short water pump. Mentioned this at the coffee-shop round table and a fellow car nut said he had a 49 pickup with the blade I needed. He called today and I went to his house and boy does he have parts. He is a street rodder and has lot of car & truck bodies. Next to the garage was the 49 Chevy pickup with a stock 216. He said the engine ran when parked and was still able to turn over by hand. He must have 20 old chevy cars and truck in various shapes in the yard and a large pole building. Well - got the fan blade cleaned and primed and just put the last paint coat on. Hope this is the end of this sidetake and on to another. Thanks to everyone and especially Brad Allen.
