It Dynoed at 493 hp and 488 torque . But #7 cylinder afr was really whacko . Figured out later that I screwed the pooch adjusting valves and #7 was way loose . Im figuring 525 hp and 500 torques . Not sure that will get me into the 10s. W2s like lots of compression and lots of duration . Neither of which I have . I could install .029 Cometics and my bigger cam but that would make it tuff to street drive with the 4 speed.
