Thanks Derf,
Since I had two cowls here I decided to do surgery on the less pretty 
one with my sawzall and grinder to allow the cowl to move forward and 
down. After the surgery I have now have 1 1/16" of clearance between the 
radiator and fan with no more tilting back of the radiator toward the 
top. I also replaced the motor mounts and brackets with ones from the 
'69 that I knew were relatively new just for good measure.
Now I should be able to take the kid to the car show tomorrow in "our" 
car. Hopefully it won't overheat with the old radiator in it.
I'll try to post a few pictures of the altered cowl setup after dinner.
Thanks again to everyone who answered my questions about this problem.
