Bill is correct in my humble opinion $8000 - $18000.
At first you listed a HP 427 and I was hoping to see Ford # as if it were a bowtie the car would be worth more minus ....
A Contemporary has a name it still will need many things in the build and the motor in combination with the car is a plus.
Original kits were around $18,000 so it may be a great starting point with a motor. Heck I would be interested as once together it will be a nice car if screwed together correctly.
Best of luck.....
