Crank Journals worn too small?
I’d use the cast crank, use a lighter piston like a hyper rite tic, and internally balance it. The balance job will be more because you need to put heavy metal (Mallory) into in. But the cast is plenty strong and then you can run the neutral balancers, flex plates, and converters. I’ve got a ‘78 440 I’m selling now. It looks almost exactly like a ‘69 including the nuetral balancer but runs a cast crank due to me having one sitting around and the application not needing a forged crank based on power output.
