The 73 340 Block, in my 74 Duster, has a forged Crank. Doubt it left the Factory that way, but it DEFINITELY has A Forged Unit. I picked up the short block, ready to roll, from a Mopar Man with a 10 second street dart. Ex Army Helo Mech. When I called him and mentioned I pulled the Solid Cam out, he Screamed " What the Hell did you do to my motor? It's a Small Block Dammit!" He had his own shop as a Business also...
