you could run the motor dry with alcohol as long as you are just making 1 pass rounds..if you were going to bracket race the car i would have something there to circulate the water thru the heads if you block it up to the bottom of water pump holes.....
you can purchase one of those scorrico style radiators ( 13x22 plastic) for cheap....ron owens can get them for you....
i ran one of these with an in- line water pump from meziere...deadenbear makes a water header for bbc and sbc,,do not know about fords...anyhow this water header bolts to the block like like a water pump but arches up and over the timing chain cover to clear cam driven fuel pump, blower belts etc.....if deadenbear doesn't sell on for fords then get a 3 way #12 an fitting and plumb you one with braided hose etc....you can get creative enough with fitting and braided line to work out your plumbing NO PROBLEM HERE..
i would definatley circulate some water thru to cool down some hots spots in the heads if anything..
been there done that , on my SBC Alcohol Injected blower motor with cam driven fuel pump...
it made over 1,000 hp at 10% over driven with port/polished bow-tie STEEL heads...ran a BDS STAGE 4 competition stripped blower...with enderle bird catcher...it was mean for a steel headed small block i assure you......THIS 1.000 HP WAS FAR FROM KILL...i was only putting 20 lbs of boost in..i could have went to 25 to 28 lbs...but this would be the limit...i feel it would have made 1200/1300 or close to it...
