1.5 HI-LIFT ROCKER ASSY KEITH DODDS FORGED

Hi-Lift at half the cost. Race engine practice at street car prices. Using 1.5 ratio high lift rockers has almost become the standard among the racers but at almost $600 for a set of full roller high lift rockers, it's too expensive for most street guys. Mini Mania also has cast 1.5 ratio rockers that are a direct replacement for the stock version AND are half the price. Complete kit includes eight rockers, adjusting screws, four steel pedestals and rocker shaft.

The most often talked about "high lift rockers" are the latest design "roller" type (see C-AHT438), but the main reason "high lift" rockers were designed was to allow easy bolt-on performance without having to disassemble the engine to change camshafts. This performance improvement is achieved with or without the "roller" added option. The standard "high lift" rockers provide a ratio of 1.5 vs. the stock 1.25. (The "roller tip" type also have a 1.5 ratio). This Keith Dodd cast iron rocker set includes rockers and special offset pedestals with high performance rocker shaft!
Produced in the same way and material spec as the 12G1221 'cast' rocker, but to CAD-CAM developed dimensions. This reduces the weight (15% lighter than the stock rocker), whilst insuring optimum strength. This reduction in weight allows lighter valve springs to be used, and extends RPM potential of the fitted spring by some 5%. Valve clearances should be opened up by .003" over recommended settings, although up to .005" can prove beneficial with certain combinations. Using the 1.5 ratio not only increases the maximum lift, but it also means that the valve is open approximately 20% more at any given point- although opening and closing periods remain the same. This vastly improves volumetric efficiency and therefore power output.
