Or instead of chroming, you could just define the cam. As in, polish the crap out of the lobes and paint the rough cast a color of choice. Just a thought. There may be some compromising with the wife yet LOL
That was kind of what my imagination said when I first saw it ... polished lobes and a gun metal gray texture everywhere else on the cam to accent the shade, maybe Super Chrome on the gear base to draw your eye downward and tie in with the polishing, and then a coat of clear to keep the bare lobes from rusting.
