Has anyone tried milling the head or raising the compression ratio?Does anyone offer cams?Has anyone ported the head and done a 3 angle valve job or even used titanium valves?I’m curious what the maximum horsepower/ torque the 961 is capable of in a race environment.What is the bore limit of the stock cylinders? I remember at one time South Bay Norton was talking about a big bore kit for the 961.
