L67 stock camshaft spec's???
I have read that valve lift is .413'' on the Intake/ & .408'' on the Exhaust.
Can anyone clue me in on the Duration at .050'', & the actual cam lift???
Thanks in advance

Std Cam specs :confused:
I can't believe that after a week there is no answer to such a simple question??? 
I was looking at purchasing the 1X Cam, but wanted to compare it with the std Cam specs first.
I think I'll be spending my money somewhere else!

Sounds about right for the stock valve lift... with the 1.6:1 ratio rockers that would equate to .258" and .255" respectively back at the cam using simple division.
I have no idea what the stock duration is.

Simple question, for GM maybe, or someone who has designed a cam for the 3800, but most people on here don't pull their stock cam out and measure its lift/duration, b/c if the cam's out for the average person on here, they're probably upgrading it anyway. I'm sure Intense has the numbers, but I don't think its their job to read every post in their public forum to see if information is needed. I don't think I would just not buy a cam because they dont respond to a particular topic on a forum, especially when the product is not theirs (GM made the stock cams, not Intense). Maybe you should email them directly instead if you need the info so bad, or maybe even GM?

Thanks MikeGS & BuickGS231 for your help.
bumpin96monte: Thanks for the lecture, although I would have preferred an answer to the actual question.
