If you buy a car already done....

I am way north 20k in my stroked 4.6 with a twin screw, Or, you could short change a build for the sake of saying that you have a big motor...
I saw this exact thing when I built the motor in my Road King, I added all the extra parts that don't add power or reliability according to the HD wrench that built both mine and my buddies, mine made 13% more HP and TQ and didn't blow up in 10k miles like his, because he short changed the build....... it's always cheaper to build it twice???
You can build it for less, but you almost always sacrifice something.
Good luck with the build, I would love to see it done.:beer:
