160 cranking psi; advance the cam or run it?

A quick calculation on engine analyzer pro determines that advancing from 108 to 104 ICL will be an even trade off of low end and high end torque output.

However with a 102 ICL the power drops off across the entire RPM range from 850RPM up to 7200RPM with nothing gained in return, not even Idle vacuum. (approximately 7 HP lost on average)

your cam is 252 @ 0.050" and 110 lobe separation. you really should consider running more like 10:1 ~10.5:1 static compression ratio to get the most out of that cam, especially when driving around town.

If you can get the compression ratio up, I would recommend installing the cam at 108 as per the manufacturer specs.
