It looks to me like a 671, but I don't see the flange on the bottom. It doesn't look a V style blower, my understanding is those are worthless. This is the only pic I have. I have requested more from the seller, but haven't gotten them. Is it worth getting?
This may help... http://www.fordflathead.com/basic_measurements.html Those rotors MAY be of value to a blower builder like Gary Dyer. He pays $125.00 per pair for 8V71 rotors... not sure with these.
No one makes any parts for them. I dont remember their name, but I bought a bunch of them about 10 years ago, only to find out, no parts interchange and nothing aftermarket works.
Looks to me like a 53-series with the through-bolt attachment and straight rotors. I'm thinking 6V53?
Krooser thanks for the link. It confirmed that Darrel was right it is a 8V53 I take it that this is worthless?
