Detailed Description

Alt Part Numbers: 1058-1A, 1058-3, 629726, 646535, 646535A1, 649322, 649322A1, 653058, 653058A1, 654084, 654084A1, 654837, 654837A1, SA629726 This high-efficiency camshaft provides 3% improved fuel economy at 65%
power, or 3% more power at original fuel flow. This is accomplished by a
slight reduction in lift, duration and overlap. The reduced duration and
overlap lessens the amount of fuel/air charge lost through the exhaust port
during cylinder scavenging. The reduced lift is incorporated to minimize
valve gear acceleration, stress and wear, thus improving durability. - Contact us for FBO/Installer pricing.
