You know Jeff, not to make myself out to be a seer, but I saw this coming. The research tools at Comp so far exceeded those of Crane that it was a slam-dunk. After looking for a cam on Comp's site, then going to Crane's site, the Crane site was a joke. It looked as it it had been put together by a grade school kid compared to the Comp site.

As far as me using Comp on the Dynosims I run, the main reason is that the software came with 800 Comp profiles installed. I just pick a cam, click on it and it appears on the DynoSim screen with ALL and I mean ALL the specs on that cam. More info on my screen than is on the cam card for that cam. With any other cam that I use on the DynoSim, I first have to try to find the intake and exhaust centerlines and the duration at 0.050", then sit down at my calculator and figure the intake and exhaust closing points, then enter them into the DynoSim manually. Not a very attractive procedure when I can simply click on cams in the software and change cams in seconds.

But believe it or not, I am pretty easy to get along with and will help anyone who is halfway decent to me. If you can get me the intake and exhaust centerlines and 0.050" duration for both sides, I'll figure the timing events and install the numbers.
