Powermaster's PN 91000 small-block Chevy PMGR starter has steel planetary gears, offers a clockable mounting block for header clearance, and weighs a mere 8 pounds. With the two sets of mounting holes, this starter can be used on either 153- or 168-tooth flywheels. Powermaster includes a starter dyno sheet with each unit. Maximum torque from this starter is 7.6 lb-ft. Multiply that by the ratio of the starter to the 168-tooth flywheel with 10 teeth on the starter, and the starter applies roughly 127 lb-ft of torque to the crank.
