Sam, Personally I think the Lunati 10510702 cam would work very well in your 455, more so than the 068 would. It has a 112 LSA so it would give good low/mid range power and idle well. Just my 2 cents. Best of luck with your Pontiac. I hate you're in a place with so few competent resources and providers.....may this rebuild go smoother than any of us think.
