I'm out at work right now so I don't couldn't tell you the model number on the fan, it is a flexalite though. After I put the engine in I put rad back in and found out some bad news that the fan won't fit between it and waterpump, should be no prob with a stock rad thats narrower. I'm going to trim a bit off the support in front of the rad to make some room and turn it into a pusher. I believe this fan is 3000cfm, maybe a bit better. Should be ok as pusher with the big 4 core rad, should know in he next couple of weeks.
