Anyone Know of Online Engine Dyno Software so I Can Test a Few Combos?

I'm a little curious on just how far off these can be. I'm messing around with a stock internals 318 and pulling off nearly 400 hp with just Edelbrock heads and intake and a cam swap with 8:1 compression. That seems like a pretty lofty estimate for such low compression to me. If it's true though I'm going to have a fun summer, lol =P.

What did you put in for the head flow numbers? That can make a tremendous difference. In fact if the flow numbers aren't real close you don't stand a chance of getting a correct hp estimate.

Rocket I have Cam Quest downloaded and like Rob said just click on the bore and stroke to highlight it and you should be able to change it. I can on mine.

If you get into the program you can change the specs of cams to make them what you want them to be but you have to leave it named their name or for some reason it won't recognize it.
