i am looking to get either a 1977 or 1978 cb750f camshaft. i'm looking for a little more lift and duration without having to spend money on a new billet or re-welded cam. the k4 "project fuzzycycle" is a very low budget build. i can pay cash or maybe i have parts you need? one of the for trade stuff i have is a set of the silver, stamped comstars from a late single cam 750
