5.4 L Engine Technical Specs
5.4 L Engine Specs. This engine is known in Australia as the Boss engine and more commonly known as a modular engine around the world , Its important to note that this Australian Boss engine was never available in the USA with the configuration as we have it in this country . The engine was assembled from parts out of various model Ford`s from the USA, Along with a list of items that were bespoke to Australian market. Ultimately caution needs to be used when purchasing parts for this engine. I have seen many people purchase and use parts that were acquired from the USA not knowing they were installing incorrect parts that caused a total engine failure.
