Glad you like the 777's. I personally hate them in a stock 103 bagger. Nothing down low. I'd take 222 or even better yet, Andrews 48 all day. Now if you're going 107/110, then you'll actually be able to feel what they are capable of.

 

I honestly feel like the 32t compensator sprocket makes up for any bottom end loss. I had the sprocket before the 777 cams so I really cannot say. And I can run with the group @ 80 mph.

 

So after 2 days of running with the 777's, I absolutely love them. If you run on the highway, which is what you should be doing in a Bagger, low end torque means nothing. My cams come in about 2500 - 3000, that's early enough. For me, I want cams that runs wild past red line so, 222's wont fit the bill.

Anyway, my adrenaline is pumping hard so now, I'm thinking of going with a 110. I just emailed my installer to see if he can rock with the FM 110 Kit . Its amazing. Once you get a shot of power you just can't stop. Anyway, guys, who here have the 103 and went with the 110 kit. What's your opinion, the good bad and ugly. Since I already have the 777's installed, this is what I'm looking at.

Personally, I know the 777s are advertised as being/working for a stock 103, but I believe they need more compression than even what a 103 twincooled engine offers. I'm at 11.1:1 with my 999-6s and they were recommended for 10.5:1.... I think Woods cams need more compression than they let on.

 

You have to just get used to life above 2500 rpm
its a blast after u get accustomed to it
and that air cleaner knocking noise

 

I get what you are saying. I've met a few riders who have installed the S&S 570 cams in 103 street glides and love them. Glad you are happy with your modification.

 

Totally agree, that was my experience with the 555s in my 96. And what's not to like about chuff chuff knock knock out of the air cleaner....

At least you guys with 103s already have factory ACRs....I had to source a set of take off 103 heads for my upcoming 107 project. At least my 2010 factory ACR harness plug in...

And yes, Wood cams love compression.. But as Fuel Moto and Bobby Wood has stated, they work just fine in stock engines.

As to 110 vs 107, I'd go with a 10.5:1 CR 107 and their B heads to match up to those 777s.

 

FWIW those cams really need more compression to realize their potential. It sounds like you are going to install a big bore kit and significantly bump your compression so they were a good choice BUT for those staying at 103" with stock compression the TW222 is better choice and makes just as good or better HP and TQ in a lower compression motor. I ran them for about a year in my 16 RK before I installed a 110 Kit with the 777's.
