It's been about a year or more since I ran those numbers through Desktop Dyno . I used large tube headers (I think) but I may have told it open exhaust. I don't recall for sure. For a carb I'm running a 750 cfm. For the Edelbrock heads I was using actual flow numbers for out of the box edelbrocks that I got off the net somewhere. If you're just selecting "wedge heads" or whatever the term is without actual flow data, that may account for the 15 hp difference.

And yes, I love the lumpy idle. That was also one of my primary considerations when I selected this cam too. I'm probably biased, but I've heard a lot of other Cobras and I haven't heard one yet where I said "I wished mine sounded more like that." Heck, if you want to hear it, give me your number. I'll call you and fire it up for ya. Ha, not sure how it might sound over a phone line though but I'd gladly let you listen if you want.
