One way to know is if it has a air intake(round with screen)on right side
dash it's a TO30. The 20 has a smooth dash.

You may have a TO20 with a TO30 engine. Does the engine have an external oil filter on the right side or is the filter inside the oil pan.

I copied and pasted Robert Sybrandy's answer to a similar question on the FENA website, below. (My 1950 TO-20, Serial Number TO-3xxxx, has one of these blocks, with the mounting bosses as Robert described.)

[i:8504da5296][b:8504da5296]Your TO-20 has a late production Z120 replacement block. The original Z120 block was replaced at some time. When production of the Z129 engine was begun, the tooling/pattern for the Z120 block was modified to create the pattern for the Z129 block. It was then possible to use castings made with the new Z129 tooling/pattern to also make Z120 replacement blocks.
The bosses for the side mounted oil filter and the generator bracket can be found on these replacement Z120 blocks but the blocks are bored and finished as Z120 blocks. The engine serial number plate was supposed to be removed from the old block and placed on the new block. The new block was shipped with new rivets to install the serial number plate. Obviously whoever replaced the block did not install the old serial number plate.[/b:8504da5296][/i:8504da5296]
