im thinkin of gettin a crane cam and lifters for my 350. ive got 285,000 miles on it with no rebuild. it runs great but just not enough power :nono: . i was wondering if anybody has experience in swaping cams and is it worth it and also will hurt my engine with all those miles on it? any help would be greatly appreciated. :shake:

Have you installed an aftermarket intake manifold? If not, i would do that also while swapping the cam to get some extra power out of it.
