No, Im not talking about the XE266HR. When I called comps tech line, that is what the guy recommended for me, but I wasnt impressed with the tech line (he didnt seem very interested, and really didnt listen to what I had to say when I was telling him my combo, he just rattled off that cam), but it has a 112 LSA, and I wanted to stick with a 114 LSA for an automatic, which I recommend. Stay away from the XE258HR, it doesnt have enough duration. The one im running isnt in the extreme energy line, but the specs. are real close to the XE266HR.
My cam is listed in their catalog under "computer compatible camshafts" as the 270HR, and its specs. are 215/220 @ .050, 270/276 advertised duration, and .533, .540 lift, and a 114 LSA.
