I’ve never run the 555 or 903 in a truck. I’ve only run the 504’s in front end loaders. Not nearly the power that the 6v-71 detroits have which is the comparable motor. These v-8 Cummins were nothing but problems. I had fun building it but glad it’s not anything I own haha

They’re really not that loud with no load on them. Yes it’s loud, but not that loud. Maybe I’m already half deaf and don’t know it

Definitely a V8!

Power, and torque…….. just enough to get it up to 2800rpm, no load. They even made a V 6. The 210 was about 185 hp, the V 6 was about 140 hp. Don’t forget, these engines had mechanical fuel systems, short strokes, they where better suited to marine, or running hydraulic drives, than variable speeds in automotive work. I worked on many of these engines in the 70’s. The 555 wasn’t an improvement. 265 ( second generation looked like a 903 ), and 903’s never really caught on. 855’s in-line 6, was where R & D money was going, and the KT. A lot of the small V 8’s where aimed at the medium duty repower market. Something that will fit in the engine bay, when the big gas pot mile’d out. One advantage over the 3208 Cat was the Cummins and Detroit engines had replaceable cylinder liners. They all got your load of gravel across town, put it that way.

No, they’re direct injection so no glow plugs needed.

Totally agree. Garbage motor.

A really bad version...😆😆

Nope, they were bummers for sure. Gotta work with what you’ve got. Once I rebuilt it, it’s been running strong since.

It wasn’t even running for 2 minutes he’s fine

I’m dead
