    Have been looking at Cam options for my 2013 103 Fatbob any recommendations between Woods, Andrews Tman, SE - About 50% 2 up and ride between 2000 - 4500

    Any mods already to the bike? Or doing any other work at the same time as cam install?

    I have heard you could do a lot worse than these Andrews cams.....

    I did a lot of research on 103"cam. .... I went withthe Tman 555 tq cams.

    Choosing cams also depends on what exhaust you are going to run. Let us know what exhaust you are going with?

    Current exhaust is Vance & Hines Short Shots and has a Sceamin Eagle Heavy Breather - All the reading on forums with cams seems to be for touring models any difference going into lighter bike - Also the cam will be all im doing No Headwork

    No offence but if you're after a performance increase, get rid of those short shots. They're only good for making noise and a good exhaust is crucial to these engines.

    I agree on your comment about the short shots Fatbat if you are chasing every possible horsepower but my 106 with stock heads, 585 cams and short shots went very well, 97hp/114tq.
    It's also about how well it is tuned

    So with the rev range the op has stated he wants the increase I would throw the S&S 583 in to the mix...

    What rev range is classed as mid range cam

    Check some cam manufacturers websites

    It depends on compression too, so for example if you had more comp than standard I would say go the 585's but with stock comp, ie bolt in cam, they may not deliver... That's why I suggest you look at the 583's... Lots of choices.... Really gotta do your homework. No one else can decide for you

    103" dyna, 9.6ish comp, stock heads, short shots, 2000-4500 range, lots to choose from, no point going high lift, SE 204's and a good tune will deliver a decent ride imo.

    True in his current circumstances but higher lift heads around .555 certainly won't hurt and the benefit is that if he wants to modify engine later down the track, higher lift heads would benefit him then.

    Last time I priced se204 cams about a year ago when the exchange rate was good, dealers were selling them for $460. I got andrews 57h (or could consider andrews 48) for $350 delivered and the .557 lift is only considered mid lift now. Tonne of midrange cams avail with around .555 lift now.

    In all honesty, op could pick any of the cams mentioned and you'd probably not even notice the difference. May as well choose on price and consider if he may want to do further engine work in the future.

    This is just a caution, I have seen a set of 57's in a stock 96 cause a lot of valve train noise around 5000 and up, 37's in the same bike revved through there without issue, cause has to be the stock springs could not keep up, I know many out there are running 57's in stock heads without issue but unknown spring pressure is another thing to consider when camming stock bikes even though the 7mm valved heads can accommodate more lift than they can flow, I prefer the lift lowish unless the heads get a massage.
    $460! Harley want too much for their cams, who do they think they are? Bob Woods or something!

    You should also take a real good look at the new S&S MR103 cams. Awesome midrange cam with excellent low-mid power which is just what you are looking for especially if you do 50% 2up.

    I've personally had the MR103 cams in a heritage softail and they were an awesome cam. Heaps of low end and midrange grunt.

    Also speak to the guy who is going to actually do the dyno tune on your bike and see what cam he recommends. As with all cam upgrades - you are not going to get the full potential without a custom tune.

    204's would be the pick of the SE cams for sure if you wanted to stay with genuine, I never have though

    So after reading alot of forum posts about cams i have narrowed it down to the Woods 222 or the Andrews 57h - any opinions on these 2 cams for my what im looking for

    Wood 222 cams are what I'm likely to use in my next bike that I'll collect within the next week. Also a 103 engine and the 222 with its earlier intake close will come on earlier than the 57h. My second choice would have been the andrews 57h. I think you'd be happy with any of the cams mentioned here and thousands of those cams have been installed in America without issues. Another lesser known wood cam to consider would be the 5-6 but it wouldn't be on song as early as the 222.

    probably hard question to answer but when are these cams likely to "come on" and when looking at dyno charts when is coming on and dropping off
