Before spending money on a new cam I'll suggest first buying a copy of the Mopar engine manual to have as a guide.
Check this site for the Mopar Engine Manual, 8th edition, P5249010, it is a give-away price if still available:

Although the 'usual' cam companies have excellent products, using a cam designed by the same people that designed the engine isn't a bad idea.

With that said, as noted above, the Crower 267HDP is one of my favorite profiles and have used it on many EarlyHemi projects.
