Difference between 378 and 379 Petes

shorter hood from what i can tell....

 

378 has fiberglass short hood, can be ordered with set back axle.

 

Depends how the truck is set up. The short hood angles down towards radiator instead of being flat like extended hood 379, could make it look taller. 377,378,379 all the same, depends on how they spec them out. Insulation package makes big difference.

 

The cabs are the same, but mounted higher on the 378. That gives the hood a steeper angle even though BBC measurements are the same between the 378 and 379 short hood.

 

You are correct. The cab sits 2 inches higher on the 378 than the 379, it is also the same on the 388 and 389.

 

Typically the exhaust on a 378 routes between the frame and cab. 379 under the frame. 378 and 357 are identical but 357 never has sleeper. Experts can't tell the diff between 378 daycab and 357. Starting with 2008 models the 379 long hood was replaced by the 389. The 379 short hood was replaced by the 388. The 378 and 357 were replaced by 367. The 357 was a "vocational" 378 with no sleeper or airide option. And If you want a challenge, try putting a 378 sleepr on a 379 cab!

 

In looking through truck paper the last few months it has seemed that 378's are more likely to be specd heavier.

 

Airide suspension or cab? My brother just bought a 357 with an AirTrac, and I just looked at one with an airride cab.
