FWIW, a lot more information would be needed to intelligently spec a cam. Head flow tables, supercharger flow map, pulley ratios, etc. as well as the rpm range you are using, fuel, blah, blah, blah. Without knowing this information, specifying a cam would just be a rectal extraction. There's a lot of that going on with specing cams, and it shows in the results.
If you really want my opinion (free and worth every penny!), change gurus and get a different cam. Don't look at the specs, just install it as he directs and run it. Results count.
Or, you could always take a poll.

OK I will ask the question. At what intake centerline was the cam designed to be installed at? It should be on the cam card or by word of mouth from the cam grinder. If you don't have this information how are you going to degree the cam in? You are taking a chance to install it straight up.

I'd go with the 116 ICL because the cam designer said to. That's one vote for straight up.
Let us know where you finally install it.

Just for the record my comment on straight up was without degreeing the cam in. If you don't degree the cam when installing it, it could be off by quite abit. I have seen as much as seven degrees and just recently four degrees on my current buildup. You just have to check everything to be sure.

I always degree the cam when installing it to make sure its correct...
