A clear pic may be helpful if you can get one.

Those are the specs for the LS3 cam which is actually a combination of the 2 different LS6 cams. The intake events are from the 02-04 version and the exhaust specs are from the 01 LS6 cam.

Part # 12574519 is actually the LS2 cam which has the same specs as the 01 LS6 cam. Where did you get the specs posted in the original post?

gm performance.
they said it came out of a new crate motor with next to no milage.
stated the duration was 204/211, that the exhaust lift was 220 something and could not remember the rest.
when the cam showed up i looked for the specs, found nothing, then seen a advertisement on the new LSX crate motors with the specs posted that matched what i had.
if the specs are wrong to what i posted then please post the right ones and what years this cam will work in.


i found it, the LS2 hint helped
200/203
500/500
unknown lsa.

Here are the specs. LS2 cam is 204/211 .525/.525 @ 116

Keep in mind the LS2 cam will not work on a Gen III (LS1) motor because the cam sensor is located on the back of the motor unless you use the LS2 front timing cover and gear sprocket. I don't see the reluctor wheel on the cam in the picture.

i guess the reluctor wheel got used on the cam that replaced this one.
i like the ray of hope you give that i can use this cam just as long as i replace my timing cover, get a reluctor wheel and sell my double roller.

oh well i think i can sell it, i have waitted this long i can wait a little longer.
