so the other day i redid the top end on this 73 ironhead, all normal stuff new pistons, wrist pin bushing, gaskets and shit. All normal until i go to start it and it will only run on one cylinder. Do a compression check 0 psi on the front cylinder. Do a leak down test passes with flying colors. So after a while of sitting around scratching our balls and checking the cam timing about 8 billion times frank asks if i have another set of cams to compare these ones with, number 3 cam was mismarked from the factory by ohh about way the the fuck off or so. See the second picture for the correct cam timing. Fun shit, i feel bad for the poor bastard who had to do this at the dealership when it was brand new.
