Its a little less drivable, it lopes till 2200. You cant lug it under 2500 or it will buck you to death. The weird thing its so much louder than it was. It pulls really hard from 2500 probably way past 6500 but I have a 6500 chip in it. We went to 6700 on the dyno and it didn't roll off. I only have 200 miles on it. I need to jet it down AFR is like 11.5 cruising 13.5 idling. The opposite of the other cam basically that's all that changes except going to the Victor from a Streetmaster. The forged crank and 2 new rods should be transparent. They freshened up the heads and new springs for the solid roller cam. Rocker arms were changed to ball-ball and new cup adjusters. New Milodon oil pan instead of the cobra pan. Same CP 10.5:1 comp pistons.
