I figure it won't hurt to ask this in a few places. I ran across some engine modelling software from Motion, called Dynomation, earlier today. I'm looking to play with some cam timing on my computer, and this looks killer! http://www.motionsoftware.com/Dynomation5.htm Does anyone on here have experience with the software? Care to offer a quick review? I'm hoping to get some opinions, before dropping $400 on software.
