Andrews 57,cycle rama 575,redshift 575,tman 600 or 555 torquester would be at the top of my list.

I've installed many sets of Andrews 54's and Woods 555's. Both are good, the Woods pull a little harder on the top end than the Andrews. I do recommend .030 head gaskets.

[saldana9]

the andrews 54 & the woods 555 are two I was looking at. Are the woods worth the extra $? Anyone have any tunes for the tts using these?

I can get a sweet deal on some s&s 570's.

SE 204 will make that 103 flat out run. You need some more compresion to get the most out of the 555 or the 54.
I would think with your set up and a set of SE204's you would be up to 90 hp and 105 TQ.
Should be able to run your stock push rods also.
Another cam that is getting some good numbers in 103's is the new SE254e. Doc in Florida has tuned a number of 103 with this cam with great results.

I have a 2012 with Andrews 54's, .030 cometic head gaskets, Fullsac xpipe, tts tuner, SE air cleaner, Fullsac 2" cores....my buddy has the exact same bike and set up except for the cams, he has the Woods 555's. He pulls me on the top end every time. Is it worth the difference? That's up too you. After him spanking me every time, I would go with the Wood's if doing it again.
But both are excellent cams for everyday riding. Good performance without substituting dependability or readability.

I'm running the 555's in my 2010 FLHTK 103.  Also has the .030 Gasket and Jackpot Exhaust with TTS.

Certainly a strong cam, however a bit noisy as many have observed.  Fuel Moto suggests that this cam isn't abnormally noisy when they do their builds. They also recommend using the woods lifters in this setup.

To get the most out of this cam, I have to run the rpms up 3200 - 4000+ .  Just a little different than I'm used to. My 110 FLTRSE3 does't seem to require the higher rpms, however that bike is close to stock.

Where did you come up with the idea that you want to do "cam only "  The single most important thing about modifying any Harley is keeping all the parts matched with one another. It's the old hip bone's conneced to the thigh bone theory of mechanics. There are so many things that changing cams will affect that I cannot go along with "cam only" You need to sit down with an experinced tech at a reputable shop and discuss what it is you want from your engine that you're not currently getting and go from there. For you to up front decide that you're only going to change cams is essentially saying that you have a complete working knowedge of your H-D engine and you know what you need to do. That you're asking for advice seems to belie that

It seems to me the average person does intake and pipes, maybe steps it up with a tune and then a cam. That seems about where this request came from.

I've heard good things on the Woods 555's and the 777's. But they do required a little more compression to get them really working. That's not saying you won't feel the difference without adding compression. The problem becomes if you're pulling the heads to add a new gasket why not just to a nice flow job on the heads since they would be off anyway.

I had a set of S&S 510G's bolt-ins put in my 88 CI Deuce a few years back, nothing else except some adjustable push rods, and it made a noticable difference in sound and performance. Granted it wasn't what it could have been but that only cost me a $1,000 with a tune. Now adding more compression, new cam bearings, new lifters and a nice flow job on the heads you're talking $3,000++. But you'll be getting better performance.

If you've got an extra $3,000++ sitting around then go big. If not, just cams will make a noticable difference. It really starts coming down to how much you want to spend. "More Power = More Money"

This site has a ton of great information on it. Do some searchs on your cam considerations here and you'll probably find the answers you're looking for. Plus, there are a lot of talented folks here ready to help out.

Let us know what you decide. Good Luck!

This may be a relatively simple solution.  I do not have personal experience but have several friends I ride with who have gone to the Ultra Limited with the 103 after bad experiences with the 2007-8 110" motors.  They have each gone with the HD 255 cam that comes stock in the 110.  In the 110, the 255 is a low end "grunt" cam.  They report that it works very well in the 103 with a better power range that it gives in the 110 and is a definite upgrade.  Not sure if it goes far enough for you but I'm sure you can find some info on this from the other forums.  I've seen several 255's for sale, slightly used.  Good luck!

That may well be and I'm not saying that it can't be done. My caveat here is to do your homework and be sure you're not going to do one thing that ends up costing you more money elsewhere. My issue is this. I personally do not believe in advising anyone as to a one part modification where engines are concerned. That's me. Many many many years of experience have shown me that it's never as simple as one item.

B - go back and read your previous post. I think you came on a little too strong.
No doubt the overall best picture is an engine built with matching components by a competent builder and then tuned likewise. Depending on your purse size of course.

But if you go outside the "tech world" that we sometimes get wrapped up in, you get many people just doing what they hear or read, intake, exhaust, cam and tune, maybe even use a dyno with that tune.

I'm guilty of it too. My bike is exactly that 90% Harley build, intake, exhaust cam and tuner (no dyno though).

And I ride with those that are the other extreme 5-7000 tied up in an engine. I also ride with many that have the minimum.
Although the bike may be extreme and run like a raped ape, it just isn't for me.

As large as this forum is now, we are still a minority when it comes to the 'Tech world"
We just happen to have a lot of the good techies right here

I don't feel I came on too strongly and here's why. A few years back before the 110 engines came out there was a LOT of chatter on this site about a particular (no name mentioned) set of cams that you install in a 103 stock CVO heads that would give you _ _ TQ and _ _ _ hp ( fill in your own numbers.)
Now, while it is true that said cams did indeed work well with stock 103 CVO heads it turned out that some exhaust systems did not work well with said heads and other factors came into play. Bottom line for me is that I saw a couple of friends with 103's already modified with PC or SERT ignitions, SE breather kits and aftermarket exhaust systems install these cams and end up having to do a bunch of other work. What they thought was going to be an under $500 mod ended up closer to $1,500. I'll risk being called a hard ass ( hmm I was a tight ass the other day - - will people make up their minds) if it means getting a member to stop and think about what they are doing. Look at the WHOLE picture.

I've got a set of take-out SE255s in my '12 103, along with an X-pipe, stage-one airbox, and TTS kit.  It works very well for me and with the dealer installing the cams (which are street legal in the 103) the engine warranty remains intact.
