I bought a aftermarket cam off this board years ago and totally forgot the part number. I installed it (a year ago) and now am wondering WTF I installed! I know it was a mechanical as I got 11 solid lifters with it, but I dont know the grind. My only clues are the installed valve lift (mic'd off the spring retainer in the head) as .428/.428 WITHOUT any lash but I cant determine duration as my cam wheel is UA. These are taken with a dial indicator off a mag base with the dial as straight with the valves as I can get it. that seemed more precise than measuring the lifter side. Any clues? Or if you sold it to me, refresh my memory so I can set the prescribed lash. Im thinking it had to be a longer duration as the lift is nothing spectacular according to some .440 lift examples. Thats about a .285 lobe lift if the rockers are a true 1.5:1.
