I don’t think so. I think your current cam while mild for those cubes is better suited to 111 cubes.
Sometimes we get caught up in the advertised rpm range to the point we forget those descriptions are tempered by the size of the engine. Volume of air is required not only by power range goals but also by sheer size. 111 cubes needs more air than a w6 is designed to provide.
The difference in duration shown between the two does show power coming on lower in the rpm range with the w6.. but I’d assume even earlier it would be quiet a bit less power. You either hold the valves open longer (duration) or lift them higher. But you need a particular amount of air. The w6 on paper to me looks like a 9.5:1 to 10:1 cam for an 88” bike.

You might go back and read my reply to your thread on the same topic 2 years ago, I'd recommend you leave the cam alone. Mine was a disappointing turd with the super E that came on it, putting a super G on it made it come alive.
At least look at a W6H, same specs with 590 lift not strangling the big cube. S&S cams are a little soft in those backed by a warranty street engines, compression bump brings those cams to life. Dave Mackie 580 has some interesting numbers 42 intake closing, 256 duration, 580 lift, spreads the wealth numbers and easy on the valve trane, Woods cams are not.
That cam is very similar to the 580S red shift shovel head Cam. And both are just like a slightly milder version of the Andrews M grind shovel head cam. I love anything between 256 and 270 duration and anything around 600 lift. Just seems to me thats where the magic always comes into play.
