Andrews 288155G 55G Gear Drive Camshafts

Gear drive uses less engine power to operate and improves valve timing accuracy over stock chain drive camshafts. Dynamometer comparisons show gains of 4 horsepower over chain drive camshafts. Sold as cams only, inner and outer gear kit and installation kit must be purchased separately. Great cam for 95in. motors. Max torque and HP at mid and upper RPm. Similar grind to TW55. Requires spring spacing. Intake Opening (degrees): 22. Intake Closing (degrees): 46. Exhaust Opening (degrees): 52. Exhaust Closing (degrees): 20. Intake Duration (degrees): 248. Exhaust Duration (degrees): 252. Intake Lift (in): .550. Exhaust Lift (in): .550. NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.
