Any advice on my 440 recipe?

Call a cam manufacturer to get a recommendation. I'm not discounting anyone's knowledge or experience here, but the cam manufacturers design cams for a living, 40 hours a week. A lot of well-known engine builders have never spec'ed a cam in their lives. They leave it to the pros.

Maybe 40-years ago this might have been true, but in today's World all you get when you call a cam company is someone that may or may not even have a clue what a cam really does. They all read the computer screen and pick one off the list. Case in point going to your local auto parts store and trying to find someone that knows anything. Trusting the guys on here that have actually had real experience with hundreds of cams is probably a much better guideline in most instances than what the guy looking at the computer screen recommends. Now I am not saying that it will be a 100% correct, however it will give you many examples to synthesize.

The #1 bit of information I can give you from doing this for 40-years is most people end up with more cam in their engine than they need for the components they have around it.
