Very cool! I'm going with the 2.9 Whipple on top of my existing 274 phaser cam in my 5.7. Sounds like I will hit right around 600hp ~550tq range with 8lbs. I was a little nervous going that high on the bottom end, but talking with the tuner I use he has cranked out quite a few 5.7's hitting 650+ to the wheels and no issues. Dodge does use Nodular iron for the cranks in the 5.7 which is quite a bit stronger than just cast iron. It seems to be proving its worth. I assume you running 12psi on the stock cam should have you well over 600hp. And if the pistons with stock ring gap can take 12lbs I now have zero concerns.Yes, still no issues so far engine wise........do have some trans slip (Auto) on full noise 3rd to 4th gear shift though.
