Help Identify Early 318 Single Plane Intake

Or Marine?

Found a lot of intakes for the Chrysler Marine 318 engines, all of that is really interesting. Mostly factory cast iron 4 bbl single planes.

At first look they looked like a real nice 4bbl intake the 318s, but then looked at more pictures of them and they jacked up the back of the carb mount to level out the carb cause the engine sits in there at a steep angle to be inline with turning then props on the inboards.

Same runners as my 2 bbl intake.

Crazy steep angle in that carb mount base.
