Hi, Dan, here's my 2 cent's worth, and I'll start off by saying that I'm not an AMC person, having never owned one, but I have been playing with inline sixes for a few years. Back in the middle 70's, I built a 194 chevy six, and used a Sig Erson cam in it with .480" lift and 256 degrees advertised duration (they didn't use the .050" standard then) on both intake and exhaust, plus Clifford intake, Holley 350 cfm 2-bbl, and Clifford headers and glass packs. The cam was listed as an RV cam by Erson. It idled very smoothly, and pulled like a John Deere from idle to 5000 rpm. Wouldn't rev higher than that, but I didn't really care. It sounds like your cam is a little hotter than the one I used, but not a lot, about 10 or 12 degrees more duration and a bit more lift. It should still be pretty streetable and give you decent gas mileage, and GOBS
