Possibly less overlap to cruise with 2.92 gears would be my guess.
They will likely pull farther in the rpm range but make less peak tq.
Either one would be fine, but add some advance around 111 to pick up the bottom end some. Wont hurt how the cam idles or cruises. They are so close really youre splitting hairs over them.

I'm 99% certain that the issues you want to clear up are the result of a bad tune.

Cam Choice #1 116 L/C +3 Hi, I agree with the KW "tech" as the new/old cams are so close.
My first recommendation would have been the #1 with the 116L/C +3 (Split Overlap)
The change will improve the D/D of your car with better Top End.

Let me ask a dumb question....is your car properly tuned? Changing to one of the other cams wouldn't make a significant difference if it is properly tuned right now....I am a bit suspect by your comment about how "Less nasty raw hydrocarbons (raw fuel smell)" which leads me to believe that a large part of your drivability may be related to the tune rather than the size of the cam.

My '95 Impala SS has a 6.5* overlap cam.....and it doesn't stink.
My '14 SS has an 18* overlap cam. Car shakes and shimmies like a bitch....but she don't stink.
Your car has only 2.5* overlap.....and she stinks. Trust me.....it ain't the cam's fault.
You have a tuning issue.....or you're running w/o cats.....or both. I'd bet a C-note on it.
