  Yep, that's it. Well, sort of.  Lift and duration match what GM gave me,
but I've got 115 degree centerline, and nothing at all for intake
centerline.  It's in the Chevy high perf. book, but there's no more info
there than what I got from the "high performance analyst" on the partech
line.  Partech is like tech. assistance for GM parts guys.  All I want to do
is install it to spec...  And yes, 24502586 sounds like the right number.
The cam and parts book are at the shop.  I know there was only one hyd.
roller cam with more lift/duration, and it wasn't emissions legal.
