Replacing a crank shaft questions

OK, so mixed use, mostly over-the-road driving. The cam size makes more sense now. It is not a big change, so not sure how much it is going to change the engine operation.

Very rough numbers: Dynamic CR work out to 7.75 with nominal numbers, the 3.58" stoke and flat-top pistons, and a guess that the heads are close to stock chamber size; pretty decent for keeping low RPM torque up.

nm9stheham, I'll take "pretty decent" anytime. what does the 7.75 refer to?
thanks again
