You'll prob find some guys that think highly of them, myself and many of my peers do not..
I personally had two Factory S&S 113" motors that both came apart with-in 4,000 miles.. One of them also blew the head gaskets in the first 1500 miles..
I broke them in 100% exactly according to the S&S factory manual..
One of them was balanced sooo badly from the factory that it actually broke my frame at the front-right motor mount..
After total break-in it felt like a jack-hammer at 90..
S&S re-built them both and I sold em as quickly as I could..
I told the buyers the story exactly as it happened,, I haven't heard back from them so I guess the factory re-builds were OK..
The best motors I ever had were always custom, not factory built..
You might consider a High-reputation builder in your area.. He will use whatever parts he has found works best for his motors and that always works best for you..
Have a ball..!!
