29. We warmed the engine up and ran the engine through a preprogramed break in procedure because of the new lifters and cam, etc. We set the timing to 35 degrees total and also set the idle speed at 750-800. Demon recommends 5-6 psi of fuel pressure for the Street Demon carb. We lightly accelerated to simulate a cruise condition 2,500-3,000 rpm and the air/fuel ratio was around 14.0; that's great for light throttle cruise conditions. After the engine warmed up, idle was adjusted again and we were ready for a full dyno pull.
