I think I will stick with a small block, probably the 318 that came from my truck or the 340 that is in my Duster. It's a '73 cast crank 340, but it IS a 340 :D I was going to save it for a Demon, or a 67-69 Barracuda, and now I have my Demon.
you can swap the 318 crank into the 340 and you will have a 340 steel crank, is the same if you use the internal balance harmonic balancer and flywheel or converter out of the 318 steel crank!
