I might take you up on that when I get back. I'll PM you later.
Well I live in Gilbert and I’ll be in this weekend. I can change it out in about an hour and a half, if you want. If I were you I would really consider the RS 468 cam. It starts pulling at around 2200 and will make over 116 ft/lbs of torque (120 on my bike).
What exhaust did you end up using? That makes a whole lot of difference in when your torque comes in and how much it will make.
I used the Fuel Moto 2/1/2 head pipe in stainless, the S&S Grand National Mufflers. I'm out of town this weekend but I might take you up on the cam swap. What engine do you have that makes 120tq? I'm also using a Power Vision tuner. I have the CVO 114" that I thought would make more power with the slightly higher 10.5:1 compression but I was wrong. I'll look at the RS 468. I'm also thinking of keeping the 777 and getting Fuel Moto to CNC the heads and bump the compression but I don't know if I'll do that because at some point I want to do their 124" big bore kit and it already has compression set from the factory deck height. I'll call them and see, maybe I'll do the whole kit sooner than I thought and just get it over with. The warranty is gone so who cares!!!

I made 120 ft/lb of torque with my 107 M8. You didn’t look at Steve Cole’s and my thread on our cam tests?
Take a look at this thread, “Dyno Tune for TTS 200 cam.....Thanks to Steve Cole and $tonecold”. That’s just a 117”, makes really good torque, if you do a 124” that’s a cam to consider. Is the pipe you bought going to be big enough for the 124”? There’s a dyno run on zippersperformance.com of a 114” making 125 ft/lbs with the RS 468 and it has a V&H pipe, probably not the best power pipe. I imagine with the header and mufflers you have you would do better than that. What are you using for an air cleaner?

A cam that rock & rolls with one exhaustcombination may perform totally different with another. In this example the customer was running V&H PowerDuals with Eliminator 400 mufflers which have a large louvered baffle this exhaust is not biased toward low end torque. The 475C cam did not like this setup, while the peak numbers were very good it was very soft on the bottom and reponse was less than desirable. We tried several exhaust swaps with some improvements, however in the end we decided to re-install the customers exhaust and swap the cam based on his original objectives and it all worked out. Again, it wasnt the cam specifically (the 475C is one of our favorites), as the end results are relative to the complete combination, one component can make or break the whole thing. For sure the single biggest problem we are encountering is bikes equipped with mufflerswith excessively large baffles, and it will affect some cams more than others.

Here is the dyno run my bike made 120 ft/lb of torque with the RS 468. I was running the stock head pipe decatted, the stock muffler cans with Fullsac cores, and an Arlen Ness Big Sucker I for the stock cover.
This is the run I made with the same setup and the wbM- 22x.
As you can see the 22x did not perform quite as well with my setup as the RS 468 did.
Here are my dyno charts from my recent cam adventures. The one with the large dip is with all of the baffles removed. It felt as bad as it looks. Really weak all over and in need of more tuning. The other dyno graph is from Trask Performance and shows the torque back where it should be but still soft under about 3k. Highway roll on in 6th gear is still better than stock but softer than I was hoping for. I'm talking with Fuel Moto about my options for installing their CVO 124" Big Bore kit.

Well the chart on this looks like the typical graph of a 107 running the 777 cam. It seems something is going on with your bike that is holding it back from making the additional power that a 114" should make compared to a 107". What are you using for an air cleaner?
