Stock Cam Specs?

Yeah, DD2000 is simple to use, all pull down menu's. the hardest part is correctly modeling the intake/exhaust components. Not to many choices there but you can still make a pretty valid assumption if you know how the manifold is designed. Ditto on the exhuast. Cylinder heads are easy since you can directly input upto 10 airflow points, along with valve size and test flow.

HP and TQ numbers aside, its useful for making fuel pump, injector choices or the like if you factor in on say a 500 hp engine, going with the 10% error, you could go best case and plumb in a fuel system for a 550 hp engine. Or if your wanting to base parts selection based on V.E its also handy. It's a good tool for making rough calculations, especially if you dont have a real dyno at your beck and call.

the downside is if you go crazy in parts selection you can put together a 2 cid engine making 2000 hp and 5000 tq at 10,000 rpm. So its easy to trick yourself if you don't make some valid choices. When I first got the program I looked for dyno'd combinations in magazines and then try'd to model the engines on the sim. e.g. a stock H.O, I found that on the exhaust side if I chose hi-perf manifolds and mufflers, it worked better than using small header and mufflers. In any event it gave me a better grasp for how to model engine combo's
