I have 2013 ultra and putting a 107 kit in and had bean at bigboyz do the street port on the heads trying to finger out what cam would be a strong cam
had a red shift 577 in a street glide it worked good but would it be as strong with the bigger bike
look at the tman 590
any help would be great
thanks

 

Look at the cams that Woods Performance has. I ran them on my 2007 Ultra with a 113ci. engine. Dynoe'ed at 120hp, and 120torque. Power band right at 3000rpm. Ran hard and fast. Loved it!!

 

either woods or zippers 650 lift cams. get ya some torque there !

 

I am running TW-777's in my FM107" and love them .... 100 ft-lbs at 2,650 rpm and peaking at 124 ft-lbs from 3,250-4,000 rpm. The 30T sprocket brings it all on really quick too.

 

GMR just did a 107 build for my bike. GMR's Genesis 577 cam. 100 ft lbs at 2300 rpm and 123 ft lbs at 3700 rpm. Power comes early and keeps pulling to redline.

 

Think of S&S 585 or 594 gear drives if your cranks good.

 

I would think ya would have picked a cam before having the heads done?? I'd sure call bigboyz because they should know what works with the heads they did and point towards a cam that will suit your riding style/expectations??? I'm a big fan of having a "goal" and putting together parts designed to work together instead of doing "science projects".

 

once the do the heads u got to ask them,who knows what chamber volume and compression u have.

 

I'm running the Wood TW-555 in my 107. I love it.

121 ft lbs of torque. I carry 100+ ft lbs of torque from 2600 rpm all the way to 5500 rpm. 106 hp isn't shabby either. No head work.

My only suggestion for you is to go with a proven kit. You'll get the best results that way.

 

Good to know. Doing FM 107 and "b" heads. Already have the tw-555 cams
