Ferris Looks great,you can't beat a big radiator,my 51 6400 ran 185 degrees thru a parade on the 4th,hot and humid won 20$ first place in antique truck division. Dual low is just right for parade speed,drove it there hot shut off and re-started several times worked good.
I figure with a good fan (OE fins have no pitch to them) and the efficiency of AL heads and FI I should be good to go as long as it does not leak. I even bought a generic overflow container cause I always hate dumping extra juice on the ground.
