Re: LS6 cam
I kinda think they did, but have never gotten a straight answer...last I knew the better part of all the cam blanks used in the market came from the same place, and *all* cam mfg's have been having cam failures. Looks like simple math to me!
Jim Lerum was the one who spotted the different lash on the 143 card...he built an LS6 and then had a cam go bad, so had another put in...he was checking out his newest cam card and spotted the 25/25 and told me about it...everything else on our cards was the same, and it even took them a while to change it on the website...but for whatever reason they call for 25/25 now...

Re: LS6 cam
That is probably lift at the LOBE. Multiply .016" X 1.7 Rocker Ratio and you get .027"
