If you can believe them (and from the article, I'm leaning that way). The thing about this engine was power really didn't come in until around 4500 rpm and then dropped around 6500 (that was their self imposed redline). Drop you a 5500 stall behind it. ~1000 rwhp. You could be very fast and very consistent with something like this. They did 60 dyno runs with the engine trying to break it. Never did ... guess they will have to try harder next time.
5500 stall....lol
I wonder how much circle d charges for that. Lol my poor lil 4L60 is trembling right now
