Holley Carb on a Ford 302?

[pcmpete]

I just got a Ford 302 marine motor with a holley carb, which to me does not look like marine carb.
Can anyone ID this carb as marine or not, it needs rebuilt but i am not going to rebuild it if it shouldn't be there.
All I know is that is says that it is re-man by holley with the model #64-5348

it does not appear to be a marine carb....first visible difference is the lacking overflow tube that curves over and points back down into the butterfly..

here is a link to that carb:

the picture they show is a standard picture, but this is an application specific carb

Haven't seen one that old in awhile. While I am not sure if it is a marine carb. It is internally vented, similar to those put on ford vans.

If there isn't a fitting for a hose that runs from the air horn down to another fitting (a 3rd fitting) in the fuel pump. Then it's NOT a marine carb. This is not a fuel delivery hose, but a safety measure in case the diaphram in the mechanical fuel pump starts leaking, it's supposed to be a clear hose.
Before you say "My Mechanical fuel pump doesn't have that fitting" That just means your fuel pump isn't for Marine use either.
That carb isn't a marine carb.

Thanks for your replies, looks like it is time for a Holley or an Edelbrock

It sure looks like you got a engine out of a ford truck.The bracket on the side of the choke housing is for a heater hose.The vent fitting was also not found on car/truck fuel pumps.

The marine Holley two barrels, (1970ish) didn't have a "J" tube bowl vent.
They also didn't use a heater hose (bracket next to the black cover) to heat the choke spring.
It didn't use a clear tube from the fuel pump to the air horn/spark arrestor,
it used a clear sight bowl on the fuel pump for visual proof of diaphragm rupture.
Number 5 in the diagram.
Marine applications usually don't use a throttle return spring.
Most factory fuel lines are metal from the engine driven fuel pump to the fuel inlet on the carburetor.
