My Turn for a Cam question - 318 Build

One thing you got to remember is the quoted powerband numbers are based on 340/360 so a 318 would be a little higher buy shouldn't make much difference at this level. The 250 cam is about equal to the stock 340 cam and the 256 is a step up. If you were willing to go with a bit of an converter I'd step up to the 262 cam but since your not the 256 should fit the bill.
