Hi there Folks!

So, I am writing because I really need to get an understanding of which truck would be best to buy. I have researched up and down about which motor is better and which ones to stay away from.
6.0
6.4
6.7
7.3? that’s pretty much my question.

 

Welcome to FTE.
I presume you are talking about diesel engines Diesel engines in the 250 or bigger trucks?
Since the engines you are inquiring about span at least 10 years of trucks, you may want to consider taking your question to the Diesel forums. There you'll find a section called "General Diesel Discussion". Post it there. I think you'll probably get more responses than you might anticipate.

Welcime to the forum!

 

My fast answer:

7.3 is great, but less power and becoming rare
6.7 is the new great, depending on year etc. they have a few more issues than 7.3s but overall seem to be doing well in the world
6.0 bulletproofed not bad, or in detuned platforms they seemed to do okay
6.4 I'd stay away from unless you want to have a new hobby

You'll probably find better answers over in the "General Diesel Discussion" forum that @Fomoko1 suggested.

Welcome aboard!

 

Moved to appropriate forum

 

they all have leg humpers and h-words


most importantly have you had this discussion with your mechanic? or will you be maintaining/repairing on your own??

 

Easier to say what you don't want...
6.4
The others either work or can be made to work reliably.

 

Nimbus, get a 7.3 PowerStroke. There are plenty of 6.7s out there, but they are newer and cost more, and have a whole lot more electronics and sensors. I wouldn't take a 6.0 or a 6.4 if you gave them to me. DF
