I'm looking for a cam to use in a supercharged Z06 (Magnacharger). The car is not a daily driver. It's got longtubes and a free flowing exhaust. Which of these two cams would work best with stock LS6 heads?

TR 224/227 .563/.569 114 LSA
XE-R 224/228 .581/.588 114 LSA

Which of the two would lope harder?

The TR cam has a fraction of a larger overlap period and will lope harder.

The XE-R would be my choice.

 

I thought overlap was determined by the LSA. Wouldn't they both have the same overlap? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
