Venom S,
I've been using Dyno 2000 and from all I've heard it is supposed to be an excellent and accurate program. You can run horsepower, torque, engine vacuum, efficiency, etc. for just about any engine you desire, even 4 cylinder rice burners and bowties. Don't have the URL, but just run a search for Dyno 2000 and you should find where to buy it. If you're going to build an engine it is well worth the $40.00 or so you'll spent on the software. How much would you spend just on a cam swap?
