So a while back I picked up a z6 head from a friend he said it had a delta 262 cam. I pulled the cam and there are no markings so I figured it must be a stock cam so I've just had it sitting around. Since then I picked up another z6 head which in fact has a 262 cam. I compared them both using a caliper measure base circle and peak of the lobes they are all the exact same except the exhaust lobe on the unmarked cam is a little bigger, about .4 roughly dont really wanna measure again. which in turn means less lift and duration of course. so my questions is does anyone have any ideas/guesses what cam this is?
I know the other is a 262 because the end is engraved. thanks in advance.
