Help identify my omc 4.3

[LassePelle]

Hi. I have a -88 4.3l omc wich is rebuildt by the previous owner. He says that the engine is a 205 hp. The plate with modelnr is lost so i am not sure about what he says. The carb is a roch quadrajet r4 4mv 17085010. It is power steering and freshwater cooling system.

Is it enough info with the carb or do i need to look for more info on the engine?
