I'm not even sure where this thread was supposed to go...but it's turned into a train wreck.
I don't kiss anyone's butt around here...but I can tell you that I do know Chris and Scott Foxwell very well and can vouch for them being straight shooters. Is Chris a salesman too? Sure he is...he believes in what he does and is very passionate about it. He's been in the industry for years and actually provides parts to many of the big name cam companies (as well as many others). I've been able to spend time with quite a few of the actual designers, manufacturers and hard core engine builders as a result of my relationship with Chris. He's earned their respect and they have no reason to support anyone they don't believe in.
Chris has his methods for selecting cams...and if you dig WAY back into his early postings on camshaft theory, he gave a pretty good rundown of his methods (with the math!) when he was first getting started. His background came from working with the late Harry Reed of Reed Cams....who was definitely one of the "thinkers" in the cam and engine world.
Yes, Chris selects lobes from the enormous amount available...and as he says...there is a LOT more to the lobe than just a few data points. He tries to pick the one that best matches what the heads are capable of and what HP/RPM range you're looking for...along with the driveability you're looking for (certain gears, trans, weight, converter, induction etc are all constraints people place on someone selecting a cam). Experience is worth a lot because he can tell you pretty much exactly what that lobe series will do in your motor given all the parameters. I've worked with a lot of cam folks over the years...and they ALL pick lobes from whatever they have available. They don't go cut a new profile just for you 99.999% of the time. The problem is if you're dealing with the MFG directly..they only have their lobes to pick from...which might not be a problem at all. They know what their lobes will do too. Dealing with someone like Chris allows him to look across lobes from everyone and pick whatever he wants. Your choices are much bigger. I've had Billy Godbold from Comp spend an hour and a half on the phone with me to work out a cam on a weird engine combo and even he admitted the compromise. Guess what? It did exactly what he said it would. I've got a cam in my car right now from Chase Knight at Crane. Guess what? It did exactly what he said it should do...and he's nailed it a couple of times before that on other projects. The cam I ran forever in my 540/555 was an Engle cam I worked out with the owner during another long cam theory discussion. Guess what....we used 3 versions in that motor as the combination evolved and each time it did exactly what he thought it would. In fact he tried to talk me out of one of them but I insisted. Guess what? He was right...and it got tweaked back to where it needed to be and ran the best times ever.
Do Chris and I always agree on cam choices? No..and you should hear some of our discussions....but it actually comes down to different thoughts on engine combinations and application that drive a different cam design for how I prefer to build my engines compared to someone else's plan. Chris is pretty good about listening to what YOU want to do with your engine and designs around that goal. Not always about the biggest HP number...but always about whatever parameters you insist on.
Anyway...not taking away from any of the posters in this thread....there's a lot of experience running in here....just figured I'd throw in my .02 worth also.

People wonder why many of the more knowledgeable members of this board refuse to post hear anymore. I see it all the time where people have asked about so and so or whu so and so won't poist here anymore....
Prime example going on right here folks.
We have a CF member who is well known in the Performance/Racing Industry and here is one of his customers sharing real honest to god results. Here he is offering insight and knowledge on the engine combination for everyone here to see.
Then we have at least (2) other CF members assailing him. Bothe of which as far as I have seen, have never shared anything worth a crap..... neither have ever offered a scrap of knowledge about engines or anything automotive related that they couldn't copy text for text out of some Hot Rod magazine article without actually understanding any of it.
It's a sad fricken day when people stand by and let valuable real world results and knowledge be run down right out the door by a couple of internet wanna be know it all's, who have never shown even so much as a single dyno sheet or time slip on anything they have ever built... let alone anything similar to this build.
