I was going to put a big block in it, but several moparheads told me the bb's unbalance the car (too heavy) and that the 340 was a great block that could be upgraded to pretty hefty power levels.
They were right, and I'm pretty happy with it.
I dislike chrome plate and billet engine dress-up stuff, I got all go and no show parts. (And a few whoa upgrades.)
When you said "1972 Dodge" I hoped it was something with a little more oomph than a slant-6 :-)
