Elite Series Rocker Arms SBF 260-351W Olds350-455

The Elite Series Rocker Arms SBF 260-351W Olds 350-455 from PRW Industries are designed for serious engine builders and performance enthusiasts working with classic small-block Ford or Oldsmobile big-block platforms. These rocker arms provide a premium upgrade over restrictive OEM units, enhancing valve actuation efficiency and throttle response.

Engineered with precision-forged steel components, these rocker arms minimize deflection under high-valve-spring pressures while maintaining tight tolerances for accurate valve lift and duration. The optimized rocker arm geometry reduces bind and friction at the pushrod interface, resulting in faster valve events and improved cylinder filling across the powerband. They are suitable for aggressive camshaft profiles and high-rpm operation.

These rocker arms are ideal for builders aiming for horsepower gains on 260 to 351W small-block Ford engines, as well as 350 to 455 Oldsmobile big-block platforms, including 289 and 400. Whether you're building a street performance vehicle or a racing engine, these rocker arms ensure reliability and repeatability in modified engines.
