Clearance for RPM Air Gap...

Your air-filter house on a 750DP, on the Ag, fit under my hood; 68 Barracuda 367, with the engine shimmed to fit the TTIs on factory biscuit-mounts. The center stud had to be shortened tho, and I raised up the rear edge of the hood slightly, on the hinges.
It didn't stay that way for long tho, until I cut a hole in the hood, and gave the engine the fresh cold air it wanted. So then I put the filter on top of the hood, in a nice oval package, and sealed the DP to the underside of the hood
If you do something like that, you will discover that the carb is not under the center of your hood,lol.
