These blocks have cylinders in pairs, i.e. the distance between 1 & 2 (and 3 & 4) is closer than between 2 & 3. The block is bent, i.e. it looks like a V8 without one cylinder bank. The 2.0 block was then designed by Saab as the reliability of the Triumph engine was so poor. The 2.0 block has the same distance between all cylinders, but is also bent as it had to fit in the same Saab 99 engine bay. The 2.3 (and the later 2.0) block was then a new design done by Saab. This block is straight as it was designed to fit in the 9000 (it did not need the bend). This block was then shortened to fit in the NG900 engine bay. -- G–ran Larsson
