I have a mostly stock 200 and a stock C4 automatic transmission in my car, and that's not going to change. (For now...) So my 200 probably never gets much above 4,000 rpm no matter what. So an aftermarket camshaft isn't going to do a lot for me. Plus with all the complaints about poor quality steel in new cams and lifters I think I'd rather buy a NOS older cam anyway. I'm just wondering which of the stock camshafts is favored around here. The Falcon Six book recommends the later ones.
