Actually, while searching the forum, I found one of your posts from a couple years ago where you basically answered my question above about the differences in duration. It looks like the cam you recommended would be a good budget choice that would be easy on the valve-train. I never realized that advertised duration varied so much between manufacturers. It does look like a more modern grind with faster ramps might be slightly more torquey but at the expense of extra noise and shorter valve-train life. I use my car as a daily driver during nice weather, so giving up durability is not something I want to do. Did you use the Perfomer cam specifically or one of the similar knock-offs? My apologies if I have stepped on your toes. Just trying to learn as much as I can.
