Default Fluidyne Cross Flow - 16 AN - Radiator - heat probs

Any help is greatly appreciated. :shock:

I purchased this radiator brand new in box - It's a 16 AN/cross flow Double Pass - 3" (2 row) aluminum Fluidyne.

Engine is a 1968 427 BBC ~550 Hp - in a 2200 lb. 4 speed manual trans car.

I am running the AN fittings direct from the front 2 ports of my intake manifold. I have 2 electric fans (pull thru) and a very air tight shroud as well. My temps are ridiculous - after 5 mins of driving - 220 - 240 deg.

I don't have any restriction (slowing the water flow) - as would be there w/ a thermostat, have tried the fans on both sides (push & pull). Have tried w/ and w/o the elbow bypass hose coming off the top of the water pump to the intake - same prob.

I know the motor is jetted properly
I know the heads are tight (not leaking thru head gaskets anywhere)
I know the timing is right

heres a shot of the radiator:


here's a shot of my application:


Any suggestions would be great...

oh.. and am running the temp sender off the passenger side center of the head.
