These cranks are forged. There was somethign drastically wrong there. I've spoken with GM engineers about the non DI 3.6 and they claimed the crank was good for over 1000 hp. That crank is similar to the DI 3.6, only the DI 3.6 has stronger pins, pistons, and rods than the non DI 3.6...
Strange. You are the only report I've hear thus far on such an issue.
