Aluminum does not cool better than copper brass metallurgical properties don't allow it, its just cheaper and lighter and almost anyone can make one and weld it without expensive tooling.
If you can fit a Taurus fan in there try that. Stand it on end with the fan up at the top and cut several 2" holes in the shroud on the lower section and screw a flap of rubber over them. This allows air flow at speed but will suck closed when the fan is on at a stop or low speed. This cools off AC cobra's with 428's and they have a far smaller compartment than a AD.
If it were the transmission pushing heat into the cooling system enough to heat up the engine you'd have a trashed tyranny in short order. Transmissions don't like to be over heated.
Your timing /fuel is not the issue because you have had this with an entirely different engine unless you used the same carb and it is excessively lean. The only similar pieces are engine compartment and radiator opening. Take the fans off entirely and run it on the highway if one close enough and see what happens. It may just cool down as you go faster, This would prove restriction of air flow is the issue.

What year Taurus has the fan at one end of the shroud ??
