Curt, I don't want to come across as a smart a$$. We can run your Desktop Dyno configurations to "What if", this, or "What if" that, because that is what it was designed to do. But the beauty of Desktop Dyno is not the peak numbers, but the whole TQ & HP curve, and how interchanging components will change this.

If you're at the engine configuration stage of your Cobra (or Street Rod, or Muscle Car) project, you need Desktop Dyno on your own PC. For the price of a decent set of valve cover gaskets, you can play "What if" with componentry until you're satisfied that your engine configuration will give you what you want, where you want it.

I played the configuration games with Desktop Dyno for a solid year before the engine went to the machine shop. Hours went into this comparing options, and printing graphs. And you will too if you do your own design work before laying a wrench on the engine, or spending a dime on parts.

Then come back to the Forum and we can share what you won't find in the books, or software.
