Have you ever wondered why your truck diesel is a straight six?

As long as you don't mind lift-off oversteer. LOL!

I've always been a fan of awd myself. Best of both worlds if you ask me.

 

Wow, did this ever make a left turn. Steering us back to truck motors, you guys are missing the grand daddy of them all, the GMC "Thunder" 702 V12. It supposedly put out 275 hp, and did a poor job. Reports of 2-3 mpg were common. By 1965, diesels were a much better choice, and the mighty Thunder V12 , of those remaining, made their way into hotrods and boats.

 

Here's what a diesel should sound like:

 

Here's another 594 side boom... being carried.



This was one of Henuset Brothers machines in their Calgary yard.

 

We've got a baby 583K in the shop right now. Them old side booms seem to live forever. Old relics now though since pipelines are dead

 

The only ones I have ever personally seen were used for irrigation engines.

 

Not a truck or tractor but personally this is my all time favorite diesel engine from Audi Le Mans Prototype ( LMP1 ) race cars from the early 2000's. Proving the old adage, "horsepower sells cars, but torque wins races".

Interestingly enough these engines were always noted as being remarkably quiet in operation. So much so the drivers often said the wind noise going over their helmets at speed was louder than the engines.

 

Them old Pontiac straight 8's would twist the wheels...

 

300 ci Ford inline 6 was a very good motor.
