| Cris Wideopen231 uses computer simulation programs, maybe he will have an opinion. As I know you're aware, there are a lot of variables the could impact accuracy.

| If you can give me bore, stroke, accurate head info,induction flo and cam open and close numbers I will run thru computer and see what it says, If you just want cam change then I can just put in set of heads close to what you have and the cam numbers and tell you what changes will do. While its not a dyno the cheap lil progarm gets real close to real world numbers when compared and given accurate info. every needs one.If nothing else it is fun as hell to just play with cam numbers, compression or head flow numbers on it. the more info the more accurate return info will be.While program will not let me paste and copy or send info,I can take pics of curves and text them.

| basically I ran Charlies cams thru program with very little difference on two he had. I also ran a tool part of program that makes cpl hundred comparison changes. It showed one that was about 20 hp higher and had less exhaust duration. Now is that iron clad. Heck no. The desk top dyno has shown some surprising results in comparing it to real world dyno numbers. I had one guy pick up .15 from suggestion on cam and another pickup nothing. Then again guy who picked up zero, his car would not change no matter what we did. The program is cheap about 60 to 70 bucks summit or jegs and fun as hell when you just want to play with ideas and see how they should work. You have to give it exact numbers to get almost exact out of it. As told Charlie. I get nothing for advertisement and make nothing for sale's Disclaimer done.

| I'm going to say unless the cam is really bad, or really good (one is perfect for the application) you won't see any difference in 2 degrees of lobe separation.
I used to be a people person, but people ruined that.
