Quote: 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?
What year 383? The pistons (all flat tops regardless of compression from the factory, I think anyways.. ) need to be physically measured to see how far down the hole they are. Some are above deck on a 383 if I remember correctly... (correct me if I'm wrong guys!)
Most ratings weren't very accurate. The compression ratios, head cc's etc that were published weren't always bang on, more times than not they were wrong!
