I was surfing the grand prix store site and noticed that the xtreme energy cams have been released for the 3800 II and SC engines. According to the specifications supplied, valve lift for both cams is over .500" w/ 1.6 rockers. Also, there are no springs available either.
Last time I went thru my L36 heads in engine machining, I noticed that the stock heads would only accomidate up to .430" valve lift (w/ the .050" clearance taken into account) with the seals installed because of the guide height. I am missing something here? I know that these can be shaved down, but according to GPS, they just "threw" this cam in without doing anything else!!!???!!!
Anyone else running one of these cams? Please let me know how good they are and if they are worth $289.00.
