BigHD1340,
Somethings to consider before you go down this road. You still have to deal with the weakest link theory. I had and still have a 124 motor in my ultra not so much different than the electra glide. The motor was basically 139 hp and 139 ft torque with no head work. Keeping that in mind your going to need / want to switch over to a chain drive and probably switch out your clutch to handle the increased power as well as look for a throttle body that will handle what your gas needs are probably 52 mm or larger.
Busting belts is an EASY thing to do and its not a covered item, so unless you can do it yourself its going to cost you approx 250 + labor to change it out when you bust your belt. I could split them in half looking like a perfect knife cut so after the 3rd belt I converted to chain drive. If your going to spend 8k on a motor why not just go to an S&S motor and then choose a fuel injection system like Horsepower inc or Zippers etc. You may also want to consider changing your end drive ratios as well whether you go to chain or stay with belt drive. Have to get the beast moving
Quite honestly you can open your intake opening to 1.800 and go with a 116 bottom end to your motor and then get the heads done by STD or someone as good or better than pick up a Woods / Andrews cam , add in a Horse Power inc 54 mm EFI with manafold , change out your pistons and boom you have a 142 horspepower 137 footpounds of torque SEEG.
Another option would be to look at Millenia Juggs and a set of heads and leave your stroke where it is and make your motor a 122 Cubes and just add in the Fuel and a set of heads / pistons.
Buying from Jims or anyone first out of the box is usually a receipe for lots of down time.
Just some thoughts to consider,
