The dyno numbers on mine are a little deceiving because I'm running megasquirt and was able to move the power up higher than stock. We were still making power at 6200 and that's where we had the rpm limiter. So I think the slightly larger cams, good rod bolts, and more tuning should put us well above 250 around 6800 reliably. Thats' really what I'd like to see and hear.
