I don't have a card but here are the specs, 284/ [email protected] 150@ .200 .575 lift.
292/242@ .050 160@ .200 .600lift.

I can't tel you Bob.
the boat is a 1999 and motor Gen v1
the cam is stamp as UD 284/292 HR12 HR14/HR15,also there is a I orT 5266 .
the UD is writhen by hand.

I did a lift check with out a degree wheel before i pull the cam out,came up with approx .356 int. 357. ex. on the cam.

I when at the shop to get the cam and double check and i was wrong about stamped #'s,it is all hand wrighting with a engraving tool.
the back end of the cam have stamped #'s 8 98 L or Z (more likely a L)
sorry if i misinformed you!
hope this will bring some light. JP.
