So I was doing motor mounts today and when I pulled the broken one out, I noticed that it was completely different from the one 225 slant motor mount I bought.
My theory is at one point, the original 225 was blown up and the previous owners could not afford another 225 so they bought a crappy 198 to put in. This would explain the 198 motor mounts in my "225" car. It would also explain the casting numbers on the side of the block being off.

Do any of the casting number guru's tell me what engine I have in here?
Thank you

Look by the coil behind the alternator on the protruding edge of the blocks deck exposed will be a number like 225 c or 198...

Understand that the 225 and 198 share the same block. It was the stroke that was less and longer rods to compensate for the tall deck.

yes, I know that they are the same basic engine with the same block, but the Vin says one thing and everything else points to another. just being curious
 
Find the machined pad on the block JUST under where the head meets the block, RIGHT behind and under the alternator. I would remove the alternator. Makes it SO much easier to see. You will see the numbers there. It will have the engine size stamped there.

Something like "Hay dummy 225 you shouldda done like MOPAROFFICIAL said"

LOL Sorry, I couldn't help myself.
 
As MOPAROFFICIAL mentioned there should be your year code, displacement and fuel type stamped right behind where your coil mounts to the block.

Then you can see if it's numbers matching to your vehicle by checking the vin stamp on the block located towards the rear of the block, seen from the passenger side of the car.

If yours is the original 70 engine, it should be stamped "F 225 R "

There is no such thing as 198 or 225 motor mounts. All slant six engines used the same mount bracket and mount rubber, in the same vehicle. The only change of mounts and brackets, is dependent on the year and model vehicle.
 
The letter before the number indicates the year
A=1965 B=1966 C=1967 D=1968 E=1969 F=1970 G=1971 H=1972 J=1973 4=1974

Alright, I had time to go out and scrape the layers of mud off of both the locations that you all told me to; Lo and behold, it is the original 225.
Thank you guys for helping me figure this out.
