Speedmaster Chevy SBC 350 1.6 Aluminum Shaft Mount Roller Rocker Arm Set .140 Int. Offset PCE261.1100

The Speedmaster PCE261.1100 is a complete roller rocker arm set engineered for Chevy SBC 350 engines, featuring a 1.6 ratio and aluminum shaft mount design with .140 intake offset. This high-performance upgrade replaces stock rocker arms to improve valve actuation, reduce friction, and enhance engine efficiency across a range of RPM bands. The aluminum construction delivers durability and weight savings while the shaft mount design ensures stable, precise valve control.

Roller rocker arms are ideal for street performance, muscle car restoration, and moderate to high-RPM applications where reliability and consistent valve lift are critical. The .140 intake offset specification is engineered to match stock or upgraded Chevy SBC 350 cylinder head port locations, making this set a direct, bolt-on replacement for engines requiring precision rocker geometry. Commonly used in small-block Chevy builds ranging from daily drivers to weekend racing, this Speedmaster set delivers improved throttle response and repeatability without requiring extensive head porting or machine work.
