Looks like this thread died out some time back.
I overhauled a 150 hp O-320 to, hopefully, around 180 HP or so with more compression and Ly-Con cylinders and indexed cam. What should I do with my P-mag? I cut the jumper to run smoother on 7:1 compression. Figure I need to reconnect at 9.5:1. Any other suggestions? Was hoping to upgrade to two EI but didn't get there.....
Updated post for accuracy!
