K.O. SWINGER
Meeting in the alley since 1976
I found this information interesting I assume it's all relevant still but who knows in this day and age. As I mentioned in the earlier post there the extruded aluminum roller tip the bodies are heavily built and wide, the hardware was all there including shaft shim pack to set it up, the adjustment studs and locks seem to be quality and I do not expect any problem with them loosening, no needle bearings, bushings appear to be steel. The rockers move freely on the shaft.1.5 ratio with 1.6 available. These were mounted on speedmaster heads and the sweep on the valve tip was pretty much dead center and needed no shimming of the shaft. They seem like a great deal but only time will tell.
