That is why I opted to go with the 280 instead of the 284 if I get a cam from MP.

I'm looking at other cams though because the main thing I'm seeing with the 280 grind is that its powerband is from 2000-5900 rpm for "mild compression applications". Now if I raised the compression by going with a flat top piston and some mill work on the heads, would the power curve kick in at a lower rpm than 2000? I also spoke with another guy that told me the CR of the 383 out of the factory was 10.25:1. Anyone agree with this statement?
