I put S&S 128 kit with WM8-408 cam and 64 mm TB to my FXDR. It is great but I think I could be happy with something less than that in my CVO street glide. I would like to install S&S 128 kit there as well but without buying new valve springs or bigger throttle body. What would be a suitable cam? I have now CR-460 but it may be too short for 128 with 11:1 Or should I keep 460 cam and get 10.75:1 kit from Fuelmoto? Or 10.75:1 kit with another cam e.g. WM8-222?

 

Good question, I'm interested in this too.
Maybe check out the CR-482 for the 11:1 (or higher) build.
I have an ever changing "budget" plan of 128"-130", stock heads, stock TB and just change injectors. I already have a PV tuner and S&S exhaust and SE extreme flow intake manifold.

 

Zippers Sleeper 128" Kit with RS472 cam may be an option...

 

Thanks for tips. CR-480 and CR-482 seem interesting but quite little info about them. Maybe CR-482 is too high rpm already? TTS 175 specs I don’t find but seem to be one option. That Zippers 472 was recommended somewhere over 468 to 128 build.

 

Lots of cool choices for sure.

 

I ended up ordering Fuelmoto 10.75:1 kit and S&S 475 cam. I hope these result to nice sound as I ordered S&S MK45 Mufflers as well.

 

Why the lower compression kit with this cam?

 

I think 10:75:1 is already enough. Less heat (even if here is normally never hot), I can use 95 European fuel etc. I think stock CVO is 10.3:1?

 

TTS will not give cam specs, they tell you what compression you need for the cam to work best. Many people have great results following this. For a big inch I would at least use the TTS 200

CR-480 is a good choice for lower compression big in builds. Darren of Shaffer Performance uses that cam in lots of his builds with great results. He has also built a mild compression big inch with the CR-482. It had good numbers too, and good curve. I talked with him about using it with more compression. Shocked at how much compression woke that came up.

Check out Dyno runs Lots of different builds with different cams. quite a few CR-480 builds. My CR-482 build.

Also check out Builds with testing of how each step helps, good info. Towards the end of this link Darren has a CR-482 build with much lower compression than I have.

 

@FLSTFI Dave I don't want to hijack this thread, but may I ask you how the streetabilty is with your build? In other words...how is it on long trips and heat? I'm in the midst of a 128 build and not sure how radical I want to go.

Thanks!
