    So does anyone know the difference between the 103 cid high output engine and the regular 103 cid engine? And do they mean higher horse power output?

    The high output 103 is the liquid cooled engine
    higher compression and different cams

    The High Output Twin Cam 103 gets more cam lift and a better-flowing airbox for more torque compared to a standard Twin Cam 103. H-D claims 105.5 lb-ft of peak torque at 3,750 rpm while 2013 models were rated 100 lb-ft of torque at 3,250 rpm. It’s now standard on Road Kings, Street Glides, Street Glide Specials, and Electra Glide Ultra Classics. The previous Twin Cam 103 powertrain will be standard in Super Glide Custom and Street Bob models.

    Not all 103 HO engines are twin cool the wide glide uses the 103 HO and is air cooled
