I posted this on one of the mustang forums with no responses... As much as it probably hurts you guys could anyone help me out?? My buddy and I just finished installing comp cams, valve springs, and bbk headers in his 2000 gt. When we cranked it up it ran fine except for the loud valve like noise.. I am guessing that there is too much lash at the base of the cam's lobes. How would i go about fixing that? Could i shimmy up the lash adjusters to compensate?
Here are the specs for the cam, everything is bone stock expect for the cams and springs.

- 'stang owner on utah boardOn second thought I beleive those paricular cams require valve relief piston. That noise he's hearing is most likely the valve hitting the piston.

Re: desperate.. help with mustang??
Thanks for the help guys.. Turns out its bad it is valve piston contact.. Since Americanmuscle.com recomended these cams for the car im praying they'll exchange them.
