Utility for plotting graph of cam/valve events?
Anyone know of an online or downloadable utility that allows you to plot a graph (with the "bell" curves of the intake and exhaust valve lift values) when given total lift at the cam lobe (or rocker), duration at 0.050", intake and exhaust valve timing events and other specifications for a given cam profile?
My cam card didn't come with a graph like that (I'm sure most don't), and after marking up a picture of my new degree wheel with the intake and exhaust valve open and close events to try to illustrate overlap to someone else, I thought it'd be interesting to see exactly what the overlap looks like from a valve lift perspective.
Here's the degree wheel picture...
