a lot of people want big gnarly cams when a stock(ish) cam will suffice just fine. i put a RV cam in my 455 buick because i didn't have the doubloons for anything hi-line and that land barge would boil the hides till hell wouldn't have it.
why short change it for a few hundred bucks when it could be damn good from the jump. also, i'd rather punch myself in the groin until i pass out than do a cam (unless i'm getting paid for it).
