Patrickt .... wasn`t trying to criticize your analysis and I hope it wasn`t taken that way . To me , your graph was interesting as I haven`t seen a cam plotted out that way before . With most cams , you only get a "spec" card. As you pointed out , valve lash has a very limited effect on the cam`s performance . but does have some effect as we used to change lash and/or advance/retard at the track as a crutch when the track conditions changed . I would suspect that the acceleration and deceleration ramps ( rate of opening and closing ) have a much more pronounced effect on the area under the curve ... and that is the cam grinder`s area .
By the way ... nice car . Looks like you have done a first class job on it !
