We had a great day on the dyno today. The motor fired right up and made 564 hp on the first full pull. Best numbers of the day were 579 hp @ 7,000 rpm and 491 lb/ft @ 5,300 rpm. The best torque number was 497.5 lb/ft @ 5,300 rpm and 574 hp @ 6,800 rpm with slightly less timing. The motor made 390 lb/ft all the way down at 3,000 rpm so I was pretty happy with that. It didn't leak a drop of oil either. We probably could have hit 600hp with a carb spacer and some dyno only timing/jetting, but I didn't see the point.
If you guys have never been to an engine dyno, I highly recommend it!
Here's a video of one of the pulls...
