Well some real world information here that I was looking for. My buddy decided on an Eagle forged crank and Eagle rods with Diamond dished pistons designed for the Magnum engine. It was more expensive than a "kit" but he was thinking of maybe hitting it with some spray in the future so I know the forged Eagle crank will be good.
The block will be at the machine shop for a while so it's going to be a few weeks until we get it back. Decided to go with the factory heads and just clean up the bowls and smooth out the pinch Going with a mild cam with some good torque to get the B-body rolling.
Thanks again for all the insight and information
Gus
