Those can really teach you something. But keep in mind, garbage in garbage out. Enter as much info as possible and it'll be pretty accurate. The biggest thing to me is showing differences between parts. That's where those programs really shine.
This is the one I got, good for heads and cam, intakes and other parts are general.

Don't get caught up in the hp torque number but the trends and curves.
There used to be Desktop Dyno 2000 free downloads floating around but I haven't been able to find one anywhere lately.
This is a really good idea and I will echo what he said.
Do not in anyway believe this program no matter what for the sole purpose of thinking that the curves shown is what your engine is going to do exactly or even similarly because even the pros will tell you that given the exact same parts for two engine built identical they will produce two engines making different power curves. Never mind by two different builders.
The program will assume perfection in the build.
Your engine could easily fall short or exceed the computers output.
BUT! The program is very good.
Follow the trends in the curves when changes are made to see how things work. You’ll learn a lot.
I used a lot of magazine builds that had dyno especially ones with head flow info or heads you could find the info for and put the specs into the program to see how it compared to real world to get a feel for it. Even though lots believe magazines lie but funny when the same builder on this site shows their results they don't question it. Even if magazines are off still valuable info since we don't have our own dynos.
