I want to go look at an old kenworth that is listed to have a "380 Cat", but I am not sure which engine it is. It is a 1977... so its a bit before my time.... I called and the owner doesnt know... just knows its a 380 cat. The truck does have a jake which rules out the 3208. Just kinda curious to know what it is before i take the 2hr drive to go look at it, so if anyone has an idea, shoot!

 

i am not sure but i think the 380 is the hp out put. it might be a c12

 

Isnt the c12 a modern engine?

 

considering the year it is most likely the A model 3406.

 

probably an A model in that old of a truck

 

Yep, 3406 A model. Maybe a B model but I doubt it!

 

Got a buddy with a 77'. His has a 3406A model Cat.

 

A 1977, maybe a 1693.. or like they said above an early 06
