How about this unit? I heard it running but they shut it off before I could get any video. Sounded like a race car, I would never guessed it was a 903 Cummins by the sound, until I saw it. It sounded awesome.

903 with headers and DD blower must be quite the sounding unit.  see they kept the emergency shut down unit on it. Brockway used the 903 a lot as well as other truck manufactures back in the day

I understand that the 903 was not that popular here in the States, BUT the Australians used a LOT of them..  Hayseed, help me out!!

They sure do get a lot of hate nowadays, but I liked the one I drove. It was in a 74 Transtar and it did a pretty good job. H.H. Moore had several 903s and he never had any major issues with them that I can remember.

They might have been the ones that had the stack on the left side of the cab, when every other truck in the U.S. had the stacks on the right.

Years later those guys with the dark blue tractors and  flatbeds had the stack on the left (Melton?)    and if I remember correctly the homely Volvos did too .  !!! fun factoid that has absolutely nothing to do with the 903 !!!

903 were used in everything and were well regarded as good motors

Then the BIG CAM arrived and they fell out of favour pretty quick for some more power and better fuel economy 

Or at least thats my take on Cummins

Lots of guys run them on small block Chevies (and of course big block Chevies) but they are not quite a "bolt on". They require a specific intake manifold or adapter to accept the blower.

And bearings and seals and a adaptor kit t o make it belt drive

But the 671 and 871 blower has been stuck on the top and on the side of a lot of wannabe hot rodders and street racers

Oh and plenty of drag cars

Not many are from a Detroit Diesel but use the 671 and 871 numbers as they are well known and the specs are loosely based on them

The 671 is the most common in Australia for young and not so young blokes and the occasional bird as well

That's awesome. I know my Vocational lab teacher did it with a blower from a DD and all he did was turn it a certain way and maybe a few other slight mods and it bolted right up.

See Joey, here's an N12  from back when the 903 was available.  Note the stack on the left of that handsome truck.Screenshot_20221025-213211.thumb.png.4dfddfbfb4377d0122279be697237483.png

I’ve never even seen one at first glance I thought it was a GMC general with a slope nose… bob
