Yes, a cast iron tranny is always gonna be stronger. The G56 is strong, BUT, the case will twist under extreme torque & horsepower and cause the shafts to try and become a pretzel inside.
But, for a guy like me with 500hp and liking to tow, it's the cats meow... If your buddy wants to swap, then a 4500 may be a good bet. There's a sled puller around here running an 06, with a 6.7 block, and a 4500.
