I spoke to tech support people at Indian Adventures, Lunati, Edelbrock, Crane,...read Jim Hand's book and articles, and most importantly, had several conversations with a machinist who does this sort of thing everyday. I decided I wanted my power at the bottom. So, he said we needed a tight lobe seperation(110 max). We may also advance the cam upon installation. I didn't want to replace my valve springs or rockers(yet) so we had to limit the lift to about .460. I also did not want to replace my converter(yet) so we limited the duration as listed. Again, wanted to power up in lower RPM range. It all made sense on paper! What I'm getting is a Lunati cam with the lobe seperation tightened from 112 to 110 degrees. They produce this particular cam when ordered so, it was no big deal for them to custom grind it. $15 charge.

Jim Hand's article regarding Pontiac cams was super informative. I encourage anyone considering a cam change to read it. I was ammazed to learn that the difference between the '068 and '041 cam amounted to only .15 seconds in the 1/4 mile. My cam should develop its power earlier than these but, will top out earlier...Won't know for sure since I don't have either of these cams. I currently have a wimpy Crane 204/214/112. I'm sure I'll feel significant improvement.
