Thanks for answering the question in a simple way.
I ask because I have a 72 duster 318 car and no sooner than a week of having it home, I found the same exact car but a slant six version with a better body. So I am asking myself If I should ditch the 318 car and get the slant six car. Either way, it's not staying original, I have a 70 340 in my garage in search of a home, and all suspension pieces and disk brake setup...... and 8 3/4
