Was going with the SE255 cams:

That said, those who have not made hardware changes to their bikes are doing the right thing by looking at dyno charts and interpreting them in a practical way, not just listening to number quotes from people. "My bike dynoed at 100 ft/lbs of TQ and 100 HP!" doesn't tell me much, like where the power comes in and if it is in a range that is useful to me. My first glance is to the TQ curve from 2000-4500rpm, and if it doesn't look right the rest of the curve is irrelevant. I looked at charts 'til I was blue in the face, but couldn't find any on some applications, like the TC96 with Andrews TW21 or Wood 6-6 with 4°-advance gear. Those were high on my list, but information was too scant and I wasn't going to jump into something half-cocked.
Honestly, I also hesitate because I'm not certain there is a trustworthy dyno tech in this area, although there are at least two DynoJet dynos locally (HD shop and one indy). OTOH, doing a dyno run might be entertaining, so I'll look into it.

You're welcome, and thanks for the compliment. It was so late when I wrote that response that I'm not sure if I was consciously trying to be be classy or just tired. Some of these recent responses left me more perplexed than vexed.

That's how I always viewed it, just entertaining to see what kind of power the bike's putting out. And that data will be a useful resource.

Iclick,
You're more like me than I thought. Cheap bastard and all. Untrusting, ya, I like that.

I've been asked this before, and the reason I haven't done a dyno-run on this setup is that (1) my butt dyno tells me that the results are positive, (2) I'm a cheap bastard, and (3) I don't care much about dyno numbers once the job is done and I'm happy. Like one respected tuner said responding to criticism of the 255 cams, "You can't ride a dyno chart." To me this means the practical effect is more important than a graphic representation, and that too often people look at the peak numbers when that only tells part of the story.
That said, those who have not made hardware changes to their bikes are doing the right thing by looking at dyno charts and interpreting them in a practical way, not just listening to number quotes from people. "My bike dynoed at 100 ft/lbs of TQ and 100 HP!" doesn't tell me much, like where the power comes in and if it is in a range that is useful to me.

Iclick, you are a real genius....
This is the kind of person that likes to up-stage (argue) when his bull **** has been called....Once again mister...you are acting like an insecure punk...looking for attention. What is wrong with?....You got issues buddy....

Is this for real? Okay, I'll play along a bit longer:
My bike has stock pistons which have a top surface that could be referred to as a "flat top." The "flat-top piston" typically referenced by HD and elsewhere is an aftermarket HD item that raises the compression ratio to 10:1 in a TC103 and 9.4-9.5:1 for the TC95 using stock heads. There is no such option for the TC96. It is a term used to differentiate it from the higher-compression domed pistons HD offers. Once again, reference the SE catalog if you need more info.
TC88: Bore 3.75", stroke 4.0"
TC95: Bore 3.875", stroke 4.0"
TC96: Bore 3.75", stroke 4.375"
TC103: Bore 3.875", stroke 4.375"
First, the TC96 has a longer stroke and a smaller bore than a TC95. Second, the TC88/95 is a totally different engine with few common parts compared to the newer TC96/103 design. Apples and oranges.
I'm certain no one will dispute that you are a producer. Have a good night.

Well here's my 2 cents. I have a stock 07 Road Glide w/Kuryakyn breather, SEST, D&D Fat Cat 2 into 1 w/ performance baffle, and SE 255 cams.
This bike only had 6k miles on it and I just couldn't justify replacing the top end. After reading IClick's and others comments this sounded just like what I was looking for.
For those that want a meaningful increase for not very much cash outlay and are more into touring than banging it off the limiter this might be it. I have less than $600 in this including install. Much cheaper if you can install yourself.
I can easily hit 100 mph going onto an onramp to merge onto the super slab which is fast enough for me. 6th gear is where this cam shines for me. Our speed limit in Arizona is 75 which puts this cam right in it's sweet spot. I can now cruise in 6th and even steep inclines are no problem. I had no problem in 6th rolling on from 75 to 100. It was still pulling hard but had to back off because of traffic.
As far as mileage I set the cruise at 78 and did a half dozen roll ons to 90 and the one to 100 and averaged 46.2 mpg.
For those of us that tour and just want the power where we ride then checkout where the power is in the curve. Anyway it put a big smile on my face and I guess that's all that really counts.

You're not supposed to show that! Don't you know the Woods cams are the shiznits in here!!
