If I'm not mistaken, it's a stock 2006 engine, right? (With the exception of the turbo.) Those numbers are pretty darn cool. It makes one wonder what would happen if there was an aftermarket that supported these engines. By comparison, the 2013 Camero SS is putting out 426 Hp. The 4200 is down 2 cylinders and over 100 Cubic inches.
With the torque converter not staying engaged at the top end. I'm assuming it's due to the pump cavitating. A problem the 700R4 and 4L60's always had. With that much power I'm guessing the trans. won't live long anyway.
Looking forward to more results. Good Job guys!
