awesomerott,
Is this a new Ultradyne (Bullet Cams), an older UD when Harold Brookeshire had the company, or the Lunati version of the Ultradyne line?

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!
