Your question is hard to make out, if your asking if a cam will increase fuel consumption then the answer is yes, meaning your MPG will go down, also the clutch you have has almost nothing to do w/cam selection, your gears are 3.42's though, 3.4 isnt accurate, but im guessing that was a typo

To the creator of the topic, if you posted with a more detail/easier to follow post, it would be easier to answer.

Well I'll answer it this way
Combustion - If you mean, the amount of air/fuel burned than, yes.
Fuel Consumption - Yes, amount depends on Cam/Tune
Compression - Yes refer to 10.5 AWD's post. (edit)

woohoo, got it. That took a while.

Ding Ding Ding we have a winner. Static compression is not affected by cam. The above listed elements affect that. Dynamic compression however is affected by cam choice b/c as the valve opens and closes the dynamic compression of the motor changes and is going to be lower w/ than static, and the bigger the cam generally the lower the dynamic compression...
