This free program for selecting a cam is a really nice tool. Allows you to choose by intended use and then allows you to run it on a simulated dyno

 

Yea its been around a long time. Its just like desktop dyno.

Its non free(now) program is much better, cam quest 6. It has flow bench tests data on many heads, stock and aftermarket.

Keep in mind, the hp/tq specs that the program comes up with are usually a bit higher than what should be expected.

Now saying that. Its usually a good tool to use to see if a certain component will raise hp or tq in which rpm range. I wouldn't use it for a total hp guesstimate. This would leave you very disappointing.

Its a bad tool for the new to engine building, or non builders, or just people who don't know a thing. I wish comp cams hadn't made the program so easy to access, but I understand it is a selling point for their products, and relieve much of their pointless work of telling people what cam will and will not work. Its just ridiculous when I here someone say their 305 will have this much hp yadda yadda. Or when I go to a dyno shop and guys are saying but cam quest said I should be making this (...whining...)
