I contacted Comp Cams and gave them all of the specs on my 2000 GMC listed in my sig. The cam they spec'd was a 208/212 @ .050 .554/.558 lift and a lobe center of 115, intake center of 111. Does this cam sound good for my setup? I am looking for more midrange power and a slightly lopy idle. Also, will I need different springs with this cam?

Thanks,
Rubie.
