Re: Dear LS friends, I need your help.
Can you link to me which cam you bought exactly? It doesn't jive that the bigger came doesn't need springs but the smaller one does?
AFAIK all of Brian's cams need at least the factory LS2/3/6 springs. If its being run on actual stock truck springs you may have a problem right there.
We've worked a ton with BT, and his cam grinder (Cam Motion) and haven't had similar problems.
