I googled the above and the first hit gave me these specs (after converting what i think is mm lift to inches lift)
intake: 0.395" max valve lift, 196.5 duration
exhaust: 0.395" max valve lift, 191.7 duration
Does this seem correct? After searchin through about fifty posts that come up when searching this forum for stock eco cam specs, I didn't find any numbers. Let me know, thanks...
Yep...that is the site. It says the pre-07 eco's had a more aggressive cam...but the HP/TQ figures did not change IIRC. It must be a rather trivial change. I guess I just wanted something against which to compare all the aftermarket.
For example...if those are the correct specs for stock...then even COMP's stage one would yield a nice gain (if installed and timed correctly)
If i remember when I degreed my factory cams i had
Intake and exaust about 385 lift and 180 duration, not sure on the lobe centers or cam centerline

am interested in this too...I have Patriot's cams which I don't even think they sell anymore...they gave me
Intake 192 @ .050 .243 Lift
Exhaust 179 @ .050 .235 Lift
I also saw the GM cam info sheet...can anybody else shed some light?
