all depends on your static Compression ratio,    have you worked that out?

9Bg really worked well on my 116 and 124 gobs of power

I'm using the 400 in my 113 and like them, no real hit just gobs of smooth torque. I would like to see what the TW-5 would do. Rosa's has used the 5 cam on big motors with impressive tq.

<<the heads  are 2" intake ,thanks pete>>

you have high output heads and IMHO you should make your 120 a high ouput build.  

but if you had those heads on your 106 with a tw5 then you were really wasting the mid/top potential of your heads.  the tw408 on a 120 is probably comparable to the tw5 on a 106 and would probably be right for you.

if i was doing a 120 with high output heads i would be looking at woods tw9fg, tman 650 or S&S 640.  Raise the CR to pick up the bottom and let the cams work with the heads to produce the power.

gotta agree with ya on this one EJ.
T-Man 650 bump the compression and hold on also what type of pipe are you going to be running??? with those heads and that valve better think borzilla. just a thought.

i know a guy whose running Baisley pro street heads , 20* domed pistons, T-Man 650 cam and borzilla and his bike un tuned made almost as much hp and tq as mine did. it will gettuned later this month and pretty sure he will be up around the 145/150 sae mark. but remember these aree not no bolt together motors..

The 6, 6H, 7H, 400 and 408 are all cut off the same C/L.
The 408 if he wants torque like turning on a light switch.
And I do agree that the F, or the others, and perhaps with 1.725 intake rockers, to really let the badger loose!! :up:

I am doing a 120 build this winter.  Baisley hy-brid heads with 2.10" intake, 1.85" exhaust.  Woods TW62g cam.  This is the same cam that Bobby uses on his personal bagger.  Dan says to use a 58mm tb with a 62mm plenum, Bobby says 55/58 so I am still thinking about that part.  Axtell jugs with 20 degree pistons set around 11.2:1 cr.  We'll see how it turns out.  If you guys have any opinion on the tb I am listening.

we were talking about cams being close in timing


look at the  woods 408 vs  t-man 662-1....... noise going to the 408`s they will drive ya nuts!!...i`m a big fan of the 662-1

look at the
t-man 650 vs woods w9f and t-man 662-2 being even closer to the w9f

now look at the S&S 640 t-man 662-3 these two 60/61  in closing cams cams will move your peak tqe over/out about 400 rpm over 52/54 closings

now look at the WT 546 intake timing....it`s close to the 640 and the 662-3 but ex timing of 52/20.......interesting cam

i use the 546 cam here

the most tqe i have ever had @ 2500 rpm`s came  from an engines with a w9f .. the most usable hp was the S&S 640..

those heads and 59 and later in closing cams will be long winded as a rule

ya get out there in the hi lift hi tdc`s ....ya really have to watch the "moving parts" things can crash :sink:

the Zipper heads will address those probs.......zippers 657 is a good one.

if ya have a 07 and up cam plate... most of the noisy cams get pretty quiet...408 is still the nastiest cam for me ...gobs of tqe early thou......not worth the chance of noise

actually i ordered two cams for myself this month WT 546 and a S&S 640 both intake. closings are close so i can run juuuuust about the same corrected compression for both.

my engine will be a 120 ci 4.625 X 4.065 using reworked stk 09 heads or 09 110 heads reworked. I have flat top or domed  pistons for either head..so compression won`t be a problem .all on a new 09 FLHX :teeth:......I have used the  WT546 on a 120 ci with 110 heads allready..........Wow

Everyone seems to be passing over the venerable S&S 625 cam 55d closing anf then there is the WT 46g cam with a 54d closing. Both .625 lift offer something. S&S reliable torque/Hp in most all engine combinations and the WT 46g is quiet..

 I was asking about your new  120 build . Are you using the S&S 4,5 wheels with the stock rod length ? And if so are the piston skirts short for the 120 build ?...thanks ...bladerunner

yes i am using the 4.5 wheels with stock length rods ,the skirts are not as short because of diameter of piston,i will do some side by side checking tomorrow and let you know how much different ,thanks pete
