Is the engine number punched on the block or do you have a engine number on aluminium plate riveted to the block?
As Jared said the engine perfix points to a 1257E motor and not a GTS one. The GTS one has 12H GTS xxxx perfix on a aluminuim plate riveted to the block.
The 1100 and GTS blocks in South Africa have the engine number on a aluminium plate riveted to the block. The 1275E block has the engine number punched on the block. All three blocks look the same. The other thing to check is how many studs the head has.
- All GTS engines have 11 studs with double springs
- 1100 engine had both 11 studs or 9 studs with single springs
- 1275E engines all have 9 studs with single springs
I hope this helps you to identify which engine you have.
