Whats that Pete?

Welcome aboard. I think that's a 359 hood with 3 bar grille grafted onto a 288. I think you could get "double round" headlights into the 80s.

 

I cannot answer your question. But here's my truck.
1991 379 ext hood
19,000lbs
Twin 200 gallon tanks
893ci turbo inline 6, 14.7 liters
15 speed tranny
Currently 2.4 million miles. In frame rebuild done at 75,000 miles under warranty. I believe I'm am the 4th or 5th owner.
As I understand it's history, it was originally used to run produce from the east coast to the west coast; then it was used in a farm setting and ultimately ended up sitting untouched for years and years. It was then purchased and used to run OTR on short stints. Then my friend purchased and fixed it up and he started a business doing air shows in small planes. Which is why it looks like an aircraft carrier (CV-64). All that is paint, not a vehicle wrap. Then eventually he retired and drove it to Florida where he lives and I purchased it from him about 9 years ago. That's why the miles seems so low.

 

@Coolbreezin that is a nice looking truck.

 

Nice.

 

Here's a photo of a 66 borrowed from @OLDSKOOLERnWV

 

That's more like a 288 I've seen. The thing was, as motors got bigger, cooling them was an issue, and the 359 came out in late '67, and had a wider front to accept a bigger radiator. Most older Petes had single headlights. This was my '72, and the last year for the smaller windshields.

 

It’s a 289. That was the 2 axle 359. Peterbilt model numbers back then were different then today. 2 meant single drive 2 axle OR single drive 3 axle.
3 always meant tandem drive 3 axle.
281/351= narrow nose (standard width) butterfly hood.
288/358= narrow nose tilt hood ( like in @oxbows pic)
289/359= wide nose tilt hood.
All the cabs were the same. They were available in both Aluminum and steel.
