One that you don't mess with.... Then you open a can of worms.Ok BigDog Bikers, What is The Most Reliable S&S Engine? 96,100,107,111,113,117,124 ect. Interested in hereing your Opinion.
The 111 is a square motor meaning bore and stoke are equal and they have always proven to be the most efficent and reliable combination most 111`s were non epa so it didnt take a hole lot to beat Bigdogs EPA 117 espeacially in 05
You reely wanta make a Dawg fast put a Non epa 124 in it and do some head work and dump the 640 cam you still got reliable long as you haint just plain stupid
