    Not sure they made an 80 in 90. Think there was a 3 cyl 3.375 bore for a couple years but most 80s I have dealt with or owned were 4 cyl 2.875 bore crossflows. The crossflows were good motors but never seen a 3 cyl 80. The 3 cyls, if like the 75-90, are very good work type motors.

    When the 3-cylinder platform came out, the outputs were 70 hp, 80 hp and 90 hp.

    After some years, they streamlined the range to 75 hp and 90 hp.
