The Mack diesel V8 was unique in a number of ways, most of all in just being the only really successful four-cycle diesel V8 designed for big trucks. It was a powerhouse from day one and developed into the legendary Mack E9, an engine still held in high esteem for its huge power output at the time (up to 500 hp) and its distinctive thumping throb of its exhaust which made it instantly recognizable when hard at work.
There were higher output versions made for marine and other uses (up to 1000hp), and today the E9 is often boosted to 3000 hp in modified racing and pulling trucks. Although Mack gave up on the big V8 in 2003, back in 1962 they sent some V8 blocks to Scania in Sweden which spawned a line of Scania V8s that are now the most powerful road truck engines with 770 hp.
The Mack V8 has a long and powerful history.
