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! -

Isnt the c12 a modern engine? -

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

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