Best way is to look on the engine serial number pad between fuel pump and distributor. No prefix is passenger, K prefix = 1/2 ton, T prefix is 1/1/2 ton truck.

The casting number, raised letters near the distributor, should be 836915. 1933 engine numbers ranged from 3367317-3964077
The car and truck engies were basically the same.
The truck engine produced a little less horse power due to intake restrictions. The car engine has tapped bolt holes on the left side for the motor mount bracket. The truck will have either no holes or will not be threaded. These holes will be on the lower left side of the block to the rear of the oil distribtor valve body.
Also 1933 was the last year to have the front fuel pump mounting bolt higher than the rear bolt.

Just found that the serial # has a T before the # 5675028 Does this mean that its a truck motor ? Will this work in a 33 Master is there any difference other than HP?

If 5675028 is the number STAMPED into the raised pad next to the fuel pump it is a 1936 engine.
Note my reply, the range of 1933 numbers and the fuel pump bolt hole configoration.

I do not about 33 Engines and am not sure on 36 Engines but on 35 Engines the car engines showed each individual cylinder as for the truck engine each individual cylinder could not be seen as the casting of the block was different even though the interior parts were the same. Gene probably knows better than me.

The 1936 engines had full length water jackets so the left side of the engine was smooth and there was a water drain cock low center. The 1935 and prior had the lower portion of the cylinder barrels exposed and no water drain.
A 1936 engine will work in a 1933 but there is no provision for mounting the left motor mmount bracket on the side of the block.
That bracket was used only in 1933 and 1934.
