If your motor hasn't been apart, and your cam hasn't wiped a lobe, THEN LEAVE THE FACTORY CAM ALONE!!!! If it ain't broke, don't fix it...The minute you swap cams, it's a crapshoot whether you'll wipe the lobes...
From your sig. I'd say you've got plenty of stuff in your motor as it is...TUNE WHAT YOU GOT!!!
What are your times right now??? Are you having any problems with your current setup??? If you feel the need to throw money away, how about you just send it to me, considering I'm laid-off from work because of the bastard terrorists SOB's!!!
