Transits are normally 202 blocks, later ones anyway.
The 4wd 200 block and the 2wd 205 are much different, differnt in many ways, they are absolutely not the same block.
The four numbers reffered to have nothing to do with good or bad but are infact batch numbers for tracing purposes, as the metal content varies slightly from batch to batch.
The cossie blocks(early ones) had thicker walls, but NO thicker than a LATE 165/185/202/205.
