Using the information on the timing card from Swoosh’s friend’s “pointy” regrind I created a lift vs crankshaft angle data set and plotted it alongside some other familiar Norton cam profiles. The subject regrind clearly has the highest lift rate of the cams shown as evidenced by the subject lift curve having the steepest slope. The lift rate and duration of the regrind up to ~ 0.050” lift is very similar to a stock CDO cam, but thereafter the lift rate increases quite dramatically. With respect to the shape of the nose we must bear in mind that there is essentially no data up there, as we have 2 data points at 0.300” lift (one on the opening side and one on the closing side) and 1 data point at the nose (0.381” lift), and nothing in between so we are relying on XL to fit a curve to 3 data points which is about as unreliable as could possibly be. Thus we really can’t say anything about what’s going on from 0.300” lift to the nose. Thought the above might be of interest to someone curious about the pointy regrind and its accompanying timing card.
