Hey Tom, you are talking about a Cougar right? You mention 91 5.0 are you taking a 302 out of the car? and if so are you using the front cover off the old engine if youre not the 91 has no fuel pump boss. Yeah the 600 will be just right. Go to eather Comp CAms or Cranes web site and they list a bunch a different cam to use then email them or call there tech guy and tell them everythig that you will be using and they will get you the best cam. As far as shorties, I have Macs and no problems others have had all kinds of problems with them, If your using stock heads you can use the factory stuff (they don't look good but they will get you by) or any number of the cheaper one Mac, BBK, Hedman. Oh and a stock fuel pump or carter , holley mechanical will be plenty.
Bill
