I have found various info on K code engines in Mercury Comets. One source shows a K code Comet to be the same as an A code Mustang with a 225 HP engine. Another source shows 64 and 65 Comets with the 271 Hp engine. If the Comets had a 271 HP engine, isn't it pretty much the same as the K engine in a Mustang?
Answers to my question would really be appreciated.
