Im not an expert but......

I have had people come up to me and ask what kind of car is that ,I just look at the front fender and point out the dart swinger on it. You know they all have to ask what kind of motor... I tell them its a 400 Big block. Some will say chevy or pontiac did not have a 400 big block they have a small block so you have to have a small block 400.
I tell them IT IS A 72 DODGE DART SWINGER WITH A DODGE 400 BIG BLOCK.
