T-Man 590 or 625
Doing a cam swap from Andrews 67 in an all-bore 107. Getting CCP double checked when bike goes in-but I had it checked recently and it came back lower (180) than what it should have been (~200).
Current set up is 10.5-1 static, R&R stage 4 heads, 50mm SE TB, Kury Powercell header with Khrome Werks 3.5" mufflers. I don't like how soft the cam is on the bottom. Granted, the CCP is likely too low as well, but pretty sure I'm going with another cam regardless. The tuner is not a fan of the 67 cam either.
So, figuring all is sorted out with the CCP, what cam and why? I've been told either will be a fine choice. This is in a 03 RK that is ridden 70/30 solo and is no longer a cross country tourer, but I do like to get it out on 2-3 day trips (1500 miles).
Also, if I go the 625 route, should I consider roller rockers?

I would like it more to the left. With the 67, it comes on like a freight train at about 3100 RPM and carries all the way out to about 6K. I like that, but I wouldn't mind it coming on closer to 2500 RPM. I would like it to still have legs past 5000 RPM though.
Thanks.
Thanks.

I used a T-Man 600 in my all bore 107. It has a early closing intake and the torque is 100 ft.lbs. at 2100 RPM, max is 123 and still has 95 ft.lbs at 6000 RPM. HP max is 121.
Compression is 10.5:1, CCP is 215. I used a HPI 55mm TB with 5.3 injectors, and D and D Fat Cat with the wrapped perforated baffle, roller rockers and Baisley Super Stock heads.
I have thought about going to the 625, but i can pull the front wheel in second now. 2003 Road King.

My build is definitely too soft down low and overall peak numbers were soft IMO. Hopefully, the tuner (is a builder also) is able to address some of the shortcomings of the original build IMO. At 2500 RPM, I'm at about 93 TQ. Peak tq is 115 and at 6000 RPM, I'm at 95 too. Max HP is 113. All around, I've always been a bit disappointed with the overall quality of the power that it makes. Both peak and under the curve. We shall see what happens after it gets another CCP check. Pretty sure it will be a cam change to the 590 or the 625. A 57mm TB is going in as well as i'm getting a heck of a deal on it. Not really willing to change exhaust as I and the tuner doesn't think that is what's holding it back. Crossing my fingers. My dyno is in the dyno section FYI.

You can check the build details and there's a chart in the link in my signature. I'm very happy I went with the Tman 590. You don't have to use 10.8:1 static with this cam. I went 10.6 and still got excellent results.

rhuff, starting shouldn't be an issue if you have compression release's. Mine will start cold with the release's closed but never hot.

The T-Man 625s work very well at 10.5-1, CCP 192-193, come on early and stay late (6k), quiet, using S&S Roller Rockers & Premium Lifters.
Another one you might consider is T-Man's "new" 585s.
