I've finally decided to buy a new upgraded 3 row direct fit radiator from chevy2only and NOT an aluminum radiator for my 283. Now the big question: What's your take on a single large 16" Elect Puller Fan instead of a shroud and Flex Fan. There's a few 16's that produce @2000 cfm's with a thermostat to kick on and off. My motor produces @ 275 HP. Not a killer engine to keep cool. I'm just not a flex fan guy OR thermo clutch fan advocate either. Do ya think one large Puller Fan with a new 3 row would cool effortlessly....

here's an example of what's on my '64... a 17" @ 2400cfm Derale fan ;)
