Check this link out for calculating the dynamic compression:

http://www.wallaceracing.com/dynamic-cr.php

A 2276 is 3.70 bore and 3.23 stroke in inches

Boost will be zero. 7.5 to 9.5 is a good range for dynamic compression, but I'd think the lower end is probably better, because of the air cooling and flat top pistons(both less tolerant of high compression).

My 2165 comes out at around 8.5:1 dynamic(it's either 8.49 or 8.52, can't remember my exact rod length), while having a static of 10.2:1.
