Once we bumped up the fuel pressure to near stock (around 55-pounds), the 24 lb/hr injectors were at 84 percent duty cycle which is optimum for proper atomization. The new combination seemed to like higher rpm and 12.9 to 13.1 air/fuel, and with a few adjustments we were just shy of 460 hp. Bob and Craig both speculated that a tighter lobe separation might have prevented the dip in torque, but idle quality might have taken a nosedive. In any event, we were all happy with the results, which brought about the conclusion to this series. But that doesn't mean you've seen the last of this motor.
