I have what I think is a 4160 carb but I cannot find an identification number where I think it should be. This carb was on a 1993, 285 hp 351 Ford / Inmar marine conversion. The numbers where the identification should be located state:

F1JL-9510-EA
R50483
2882#

This location is I think called the air horn on the right side? Nothing in on the left side. I'm not familiar with the terms but it under the wall under the air cleaner on housing outside where the butterfly valves are located.

I would like to get an identical replacement to this carb.

Thanks
