Need Help With 318 Build

Thanks for the responses. I just found out the car is coming with an 8 3/4 rear and factory front disk brakes with ac. I am not for sure of the trans or converter in it. It is a second owner car, with the second owner knowing the original owner for quite some time from what I understand. I'll start looking for parts once I see numbers are on the block and heads. It might be a mystery motor for all I know. Thanks again for all the help. Any additional info will always be welcomed. I'll start looking for parts that I will need.
