will this build's compression be ok?
Hi Guys,
I'll be fitting these components to my bob soon, just want to check compression will be ok.
not after anything wild, just give her a bit of a tickle !
1. S&S 106 big bore kit
This kit gives 10:1 compression ratio with stock heads (and I guess this is with the head gaskets that come with the kit which measure 0.045")
2. S&S 583 CE EasyStart Cams
Optimized for use as a great over-all cam in the SoftailŽ/ DynaŽ lines, but can be used in any 2007-up big twin model.
Provides strong low end torque and horsepower that you can really feel.
Strongest from 1500-5000 in a Softail/Dyna application.
3. Stock Heads (for now)
4. 0.030" head gaskets

Me thinks that 583 will carry waaaaaaaay too much ccp underneath that 106"er.
A .570 would be a better choice, and even then, a .030" head gasket won't work, unless of course the chambers are larger that 85cc's.

So even with the 0.045" head gasket the ccp will be too high with the 583? What would it be?
Being an easy start cam doesn't help?
Sorry for the questions, I had better research ccp a bit more...

Scott is right; corrected CR and CCP will be nasty. TMan's 590 would work pretty well with the SnS 106" kit.
