If your going to keep the 3.27 gear I would not go with the CC306. (lt1 speak for the 230-244 cam). Get a XE cam. They are much better. Like the 09-423-8

224/230
502/510 (get it on a 112lsa)
http://www.compcams.com/base/process...Known=08-423-8

or the 432-8 if you plan on having about a 3.73 gear

The LPE cam designed for the Superram would also be good. It's like 219/219 .525"
