Help Choosing Correct Cam

Not bad once it gets above about 2800, but is weak in the low-end and I'm surprised it isn't better. This is based on this one chart, and we don't know anything about the bike, like what pipes were installed, etc.
 
If you want to stick to the Andrews line you should put the 48H on the top of your list. The 21H is okay but the 26H will not likely retain the low-end of a stock cam unless you bump the compression. The 48H is a direct answer to HD's stump-pulling SE255's.
 
There are likely a boatload of cams you could be happy with.

But as you search out the dyno charts, look for charts with your model year bike. The gearing can make a difference on the paper.

I was not a fan of the HD 255 until I put some in my brother's 2009 last saturday. It put the power ride right where he rides and is just as quiet as stock as far as top end clatter. And we did it for $170 including the new bearings. Those 255 cams are cheap used.
 
I suspect most of the detractors of this cam have never ridden a bike with them installed, as the effect is somewhat more enlightening than you might think by staring at dyno charts. The power is where I ride and with these cams I don't need to rev beyond 4500 rpms, but if you do there's still power above that point. You can buy them on Ebay for about $150 as low-mileage CVO pulls, and there is no reason to be squeamish about installing used cams that came from a normally running engine.
 
If installing on your 08 King, depending on how many mile you may want to replace the lifters. My wrench reccomended this @ about 20,000 mile when he installed my SE 255's.
 
I totally agree with this statement...I had tw6-6 cams in my flhtk and wasn't happy...they felt flat below 3k...were noisy....and the bike tended to be hotter..........I went to the se255's and they felt significantly stronger throughout the rpm range.......I've heard on here that the se255s fall off in higher rpm range......that wasn't my experience...of course the 255s got the bike moving quickly with the down low torque I didn't need to rev it.......I had to rev the tw6-6's higher because I was still trying to get the weight of the bike moving.......

with the sse255s I could shift sooner......the bike ran cooler.....and the noise was about like stock......seat of the pants the bike feels significantly stronger......
