"clones"

How about the situation that i'm in.
I want to build a car or 2 and have slant6 318 340 and 360 abody project cars to choose from in the same condition. I want to build a car that is personalised not butchered and cannot choose between them. Cars range from a '71 340 duster to a '75 360 dart sport. All of them don't have the # matching engines with them so what do i do?
I have about 12 good project cars and the rest are parts cars only about 40 cars totaly.
I'm not looking to clone anything at all.
Just have some fun!
