The V8 was made in 3.5, 4.0, 4.2, 4.3, 4.4, 4.5, 4.6 & 5.0 litre versions all bar the 3.5 and 4.4 used 94mm bore, the 3.5 and 4.4 used 88.9mm. The 4.4 was developed by BL's Australian operation and had an extended block to accomodate an 88.9mm stroke making the engine square. It had the potential to be the best enlarged version of the engine. It was lost when the Oz operation was closed down.
