I need a part # for this Comp Cams cam:

Comp Cams Xtreme RPM grind

.563/.563 Dur@.050: 224/224 LSA: 112

 

That is the TR224 cam. You can find specs, pricing, and even dyno sheets for the cam at http://www.thunderracing.com/. That is probably the best all around cam you can put in a LS1. It's been the cam that all others have been compared to. Excellent choice!

 

So this cam is only available only through Thunder?

 

No. Others have copied it or very slightly altered the specs. It is a Comp grind so you could also order it through them. I personally find it better to buy from the vendors who support this website. Customer service counts a bunch and Thunder Racing is one of the most respected companies around that specialize in LS1s.

 

The Comp Cams lobes numbers are 3715 for a 224 duration at .568 lift so you would ask for that lobe number on the intake and the exhaust and pick your LSA and I usually set our cams up at +2 advance.

The difference between .563 and .568 lift is minimal.
