I got these from this site

http://www.smokemup.com/tech/ls1.php

I think that some of the duration and lift numbers are backwards, I corrected 2 of the duration specs in my list.

Part# 12565308 $234 from GMPD

hog your specs are off, those numbers are not at .05 duration, and some of them are wrong.

hog

Those arent my numbers, they are from the Smokeem up site.

Actually those are numbers at 0.050", they are certainly not the duartion numbers at the lash points.

BTW, your year breaks are incorrect, they didnt have 2 different cams for the 2002 LS6 like you have stated, there is only 1. Additionally The 2001 LS6 cam is different than the 2002-2004 LS6 cam.

Looks like we both need to check our sources.

Does anyone here have concrete cam numbers for the GEN 3 engines???????????????????????????????????????????
