Ok, a couple of notes and thoughts.

*351W and 302 can use the same cam. You would also you use the same firing order as you're using now. 13726548.

*You're not making power at 8000 rpm with the cam you're using now, or the cams that you've listed. (They don't have enough duration, lift, or a tight enough lobe separation to do what you're wanting to do.) I don't really know why you feel it necessary to stress the motor that hard, but you'll need a lot larger cam, better flowing heads, lot heavier valve springs, and a lot better valvetrain to make reliable power at 8000. All you're doing now is exercising the tach needle and putting undue wear on the engine components.

*If I could make a suggestion, I would suggest that you take a step back, figure out what you really want to do with the engine, then contact an engine builder that does this every day and just have him set you up with all the parts necessary to make this an easy swap. Keith, Barry, or I would be more than happy to help you with this.
