Glad to here those are holding up well. I may be doing a cam change sometime in the future and haven't fully bit the roller bug with the cam selection. I ran a 700 lift in a small block with street miles and had lifters rebuild every 5 yrs. Don't really want to get back into that maintenance gig again with all the expense along with it. I may change my mind on this when the time comes, but right now i'm happy with SFT cams.
