I have a mystery Solid cam that was pulled from a high effort 440 drag truck built about 20 years ago... I friend who was cleaning his garage passed this down to me knowing I have several big block mopar builds in process. He could not recall the make or specs of the cam other than thinking it might be a Crane Solid cam. I measured the lift to be at 525 at the valve. The owner/racer claimed his 82 d100 ran low 11's with this cam. Any how, here are a few pics of the markings on the cam... can anyone decipher the numbers? Any feedback will be helpful in deciding if this is worth saving or using.

Thanks
