Inliners International Forums General Discussion Hi Performance Stovebolt rocker arms different between 235, 261?

I was always told the 261 rocker was "stronger".I never noticed a difference,but didn't really look that close.
You mention the 261 being a "low RPM engine".Not really true...Driving old trucks with heavy loads and limited power meant if you needed road speed,the engine was run up against the governor for periods of time.Passanger car engines are almost never run wide open at 3200 rpm for more than a a few seconds.
