Yep, my 72 Z was jetted like that. The same as our 69 Z with a much smaller engine (68's in the primaries). Which just shows the direction they were going.
I currently run a stagger jet setup in our 69 Z with it's 302. 72 primary on the driver side and 70 primary on the passenger side. I generally stagger the rear the same but currently just have 76's in both rear. A track day I'll change it.
Living at 5,000 feet elevation this actually returns very good drivability and respectable gas mileage (15 around town) and is slightly on the rich side. A good thing since we drive it down to sea level semi regularly and I know the engine is safe there, I don't have to fool with it. With the 5 speed it gets just over 21 mpg highway.
