I went to a local speed shop here yesterday and strapped the vert down on a chassis dyno. I did three pulls and they were all nearly identical. The best one showed a max RWHP of 380 @ 5,250 pm and a max RW torque of 460 ftlbs @ 3,250 rpm. This is nearly 100 RWHP above my previous motor that was in the car when I bought it. Overall I was pleased with the numbers considering it is a mild to medium build with manifolds for the street. The operator estimated my crank HP at around 450. He said for comparison he has had several new Challenger SRT8's (6.1L) on his machine and they come in at about 340rwhp. Thanks to those here that helped with their expertise and info for my build!
