Anyone know about a Mack 475 turbo with 5 speed manual (its in a ' 75 R model fire truck) where they a good engine ,reliable ,fuel economy, etc?

A 475 would be a non-turbocharged (normally aspirated) Scania-Vabis D8 rated at 140 horsepower. For it's intended purpose, it was a great engine.

But that's an engine from the 1960s.

The turbocharged engine you are speaking of (1975 vintage) would be a 477 (ETZ477), rated at 210 horsepower (Scania-Vabis DS8).

This fire apparatus is a model R487F ?

Once again, when spec'd appropriately for the application intended, it was a superb engine. Dependable and economical, it was a popular powerplant in its market segment.

Incidentally, Scania-Vabis (now simply known as Scania) was one of the first engine makers to furnish a centrifigal oil filter on their engines.

The Mack-Scania relationship goes far back. (http://www.bigmacktrucks.com/index.php?/topic/34624-mack-scania-cooperation/)
