SHM Stage II Billet 4V Cams

from what i've heard, SHM stuff is overpriced. and like Saleen has some bad customer service. If you're gonna drop the coin on SHM cams, get the FR500 cam kit for that coin. comes with cams, springs and everything.
 
who said i was gonna buy from SHM?


now someone has got to know the answer to my question..i just wanna know about the hydrocarbons, nox, and co counts after installing
