I have a quick question about the power output versus the compression ratio. Here are the specifications for the 383:

Stroke: 3.75"

Bore Dimater: 4.030"

Piston CC: -16 CC

Piston below deck 0.010"

Head gasket compressed thickness: 0.029"

Heads: 62 CC Iron

My static compression ratio is 10.1:1

Here is some dynamic CR information:

Static compression ratio of 10.1:1.

Effective stroke is 3.43 inches.

Your dynamic compression ratio is 9.28:1 .

Your dynamic cranking pressure is 192.45 PSI.

Am I leaving power on the table by running a static CR this low? I think I am, but how much? Any help would be greatly appricated.
