I was hoping for around 550 hp but could only muster 493 .
Torque was good running 428 ft-lbs by 3800 and 482@ 4700 !
Power dropped off abruptly at 6200 which surprised me for W2 heads. View attachment 1715816539
Can’t remember what this is going in and it’s intended use? Considering the cam with those @.050” duration numbers making peak HP at 6200 it seems spot on.
Overall I’d think you’d be quite chuffed with it, I know I would be! :thumbsup:
