cannot find it any where here are the numbers on front N51P on top and RRN 268e 280f 110 I realize these are duration numbers and ls .The problem is i found the same specs on a flat tappet cam im not sure what lift it is I was told it was a solid,and the motor has solid lifters in it not sure if they are lunati anyone know this camshaft? Their are also some numbers on the rear of the cam 449566 on top and 95K1R on the bottom .I am hoping it is a solid roller and this person wasnt as stupid to put a motor together with solid lifters and a flat tappet cam

Pull a valve cover and look down the pushrod holes unless the oil return holes are bigger and see if it is a flat tappet or roller. If you are not taking it apart, you can take off the pulley and put a degree wheel on it and use a dial indicator to find out what the duration and lift is as well as lsa.
