Just following along to see what I can learn. One thing I'd do Chris is take your existing radiator to a local radiator shop that you trust, and just talk with them about the core that was in it - vs. what they can put in a diesel radiator shell. I didn't have the Corvette radiator - but I did find that between the newer, higher fin/inch core being thinner than the old ones, and offsetting the thinner core to the front of the tanks, I picked up almost 3/4" worth of clearance for the fans AND increased cooling capacity.
