Thumbs up

I just happen to have ordered Desktop Dyno 2000. I'll run it for you when I receive it. It should be either the end of this week or early next week.

just don't expect that program to be 100% acurate. There's too many variables in the real world.

Save that $44 and take it to the local dyno shop when you are done with the rebuild, leaves no questions as to the results.

Part of the idea of a program like that is to find the combination of components that will work the best together, without buying all of them and taking them to the dyno. It can be fairly accurate, too. I read on this board somewhere, dont remember where, that the actual dyno test on someone's motor was within 3 hp of what desktop dyno said.

What's the CC on your heads? There are a lot of C3AE heads in the book. Are they C3AE-A's or C3AE-B's, or what?

Edit: I've got my Desktop Dyno 2000, so I can run it for you now.
