Can Anyone Help Identify Engine?

I bought an old log splitter. It has a horizontal shaft engine on it. I'll try to post pics after this if I can. The shroud says it is an 11 hp Briggs, Model 272707 Type 0136-01 Code 78030. From what I have seen so far on the web, these engines are vertical shaft and not horizontal. I'm not sure if this shroud is even for this motor.
The way the engine sits now ( shaft horizontal ) the oil fill cap appears to be in the right position, facing up. If the engine sat shaft vertical, the fill cap would be facing forward and 5 inches deep under the cylinder and head with only the height up what I think is the sump as clearance between the motor and whatever the motor is mounted to. This has me totally confused as to what I have. Can anyone help?

If the photos come out okay, if you look at the rear of the engine, just above or behind the fuel line, you can see the little screw oil fill cap. If this engine were mounted with shaft vertical, I can't believe you could ever get oil into it. And when you look down into the oil fill hole, the oil is wayyyyyy down. I can't see filling this to the top of the fill hole. I think that would put way too much oil in it. Can anyone help with identifying this and tell me what I have? Any help is greatly appreciated.

Don't see the second photo so I'm posting it here.

One more try.

I have 3 252707s and they mine are vertical shaft.
I have a feeling you have a cover from a 252707 on a horizontal engine.

I am not at work, so don't have parts books handy, but Briggs did make some horizontal shaft 11 hp engines. I can remember one on a 'Workhorse' Wheel Horse-(a budget Wheel Horse) that I fixed once.

Lots of those engines had an extended dipstick that went where your oil fill cap is. It stuck up about as high as the fuel tank. Others had at least one cap front or rear low down on the side to check or fill oil. Some had a cap on both sides.

You have a horizontal engine with the shroud off a vertical shaft
engine. It is very common for the shrouds to get swapped.

I have a Snapper tiller with an MTD shroud.
Briggs made both 8 and 11hp horizontal engines.

Hi I have a couple of B&S 11 hp horizontal engines model 252417 both have a long oil fill tube and dipstick comes up to about the top of the cylinder head on the PTO side on other side from the carb.

Well, I'm glad that it seems I don't have a vertical shaft engine mounted on its end. If anyone has one of these engines with the proper dipstick, it would be a great help if they could measure to see how far below the oil fill hole the oil level should be. I can wing it from there until I find a proper dip stick.
Also, pulled the carb off today and it is really good at holding water. I don't think it is salvageable. I went searching and there seems to be a whole bunch of carbs that look identical to this one but with about a half dozen or more part numbers. I couldn't find an exact match but every carb I saw had the adjuster for the air intake butterfly on the opposite side as mine. Mine sits inside between the carb and the block and all the others are outside. I don't know what model this carb is. It seems all those carbs that are identical say they fit 7,8 and 9 HP engines. I was thinking that maybe I could get one of those and just switch the butterfly shafts providing the shaft diameter is the same. Or could I get by without using the existing linkage? I think the ones I have seen would work provided that the mounting plate on top that bolts to the intake elbow is the same size. Does anyone know if all those carbs are identical in size at the intake plate? Also thanks for the replies to my post everyone.

Hi the 7 8 9 hp carb is too small, this is the model carb needed for that engine
