GT6 Cam regrind

["Scott Janzen" <s.janzen@comcast.net>]

I have a reground Triumph cam in the race car, which has the following
numbers stamped on it at two different locations:

MC 25225    C

88311399

Cam provides about .430 inches of lift (assuming the stock rockers are 1.5
to 1, which is what I recall).

The question is, are these  Triumph numbers or something put on by whomever
did the regrind that I might be able to use to identify the re-grind specs,
i.e., what the cam timing should be?

Any help would be appreciated.
