103C.I vs 106/107

I have read a lot of threads on here about the builds they don't seem to be much different in power. Give me your setups with TQ and HP. I am trying to decide the cost isn't much different so I am trying to make up my mind. Thanks in advance.
I already have 94hp with 100TQ.

No such thing!!

Mine is a 4 1/8" bore 4" stroke 107" and made 115hp and 122tq the last time it was dyno'd. I bumped up the compression and added nitrous so its going back for a tune next week.

If you want more power check out the fuel moto 107 build and OdiousBarbarian sounds like he is having great luck with his hillside 107 build as well. Those are good numbers he has. I am just running the stock setup at the moment with pipes and EFI box so I am not anywhere near the numbers you have even now. Good luck. Post results when you decide on your build.

I have a V&H comp pipe with V&H A/C and a redshift 575 cam. The cam isn't exactly what I wanted but gave me good power. I will probably change the cam and exhaust eventually.

I agree with that! I've also seen some great numbers with a 103". It's the builder that seems to make the difference.

That Fuel Moto build you mentioned, if I recall, was about $2800 and included the exhaust, programmer and A/C. Pretty reasonable in my book to take a factory stock bike to that level, which was about 120/125 HP/TQ if my failing memory serves me correctly. I wish someone could bring that few month old post back up. For sure don't trust my recollection!
