Stock Cam Advertised Duration? Apologies if this is easily found somewhere--I've searched for several hours. I would like to know the stock cam specs for a 2002 LS1, including advertised duration.

Re: Stock Cam Advertised Duration? Thanks for that, but that only shows .050" lift figures. I'm looking for the advertised duration to use in Intake-Valve-Close (IVC) event timing calculations.

Re: Stock Cam Advertised Duration? Add 50 degrees to those figures and you will know pretty close what advertized duration is. A better question is why do you care? The stock 2002 LS1 cam for an Fbody is a truck cam! If you have a Tahoe it has the same cam in it, nothing special here.

Re: Stock Cam Advertised Duration? Calculating the dynamic compression of a stock 2002 LS1 might be a worthy exercise, it might not. To complete the calculation requires precisely knowing Intake Valve Close, measured from the advertised duration.
Many thanks!
