Im thinking of putting a cam in my 87 GT this winter. But the thing thats stopping me is that i would be putting a new cam on 130,000 mile bearings. I realize i cant go with a real radical cam because i do not have Mass Air. What do you guys think, would i throw my bearings.. or something else if i put a new cam in on those old bearings. If i was to put in the cam i would go with everything, Cam lifters, pushrods, and maybe roller rockers. What do you guys think, should i?
