Actually to the first doofus, that is relative. you own a classic car with a v-8 and expect to get 15-22 mpg, so it is not a Jetta or another gas miser.
Still, it is from the Pontiac V-8 family and was in production from 1968-1979 (must have bben a reason). It has a smaller bore and longer stroke than a Chev 350 and with a2 bbl bad mileage, with a small 4bbl carb and mild tune, you can get nearly 20 mpg out of this. Congrats on having a classic Ponticac and keeping it going.
http://www.pontiacpower.com/ try this link and others for Pontiac peformance building and parts. Much better engine in mild form than a chev 350. Generalizations about it being a 10mpg hog are relative to the state of tune.
While todays combustion technology and especially fuel injection-efficiency has increased , yet it is till true that increases in power are the ability to burn more fuel. BTW ,in good shape the car is worth five figures.

I had a 69 GTO with 400. It got 15 mpg hiway and 11 in town.
Then I built it 60 over and cam. Milage went to 11 Hiway and 5 in town.
They are good engines but will not take a high rev. I blew it every time I went past 5500 unit I built it and left the windage tray out. It would then take 6000 rpm without blowing.
P.S.- The Pontiac 350 IS a BIG BLOCK! Same block as the 400 with a smaller bore.
Drove this care for 12 years - 12 engines (I ran the SH*T out of it) but no fault of the engine.

How does 10 miles per gallons fit you?
I owned a 1979 Camaro Z-28 with a 350 cid motor. It is a nice classic car, but I would not recommend it as a daily driver.
If you are restoring it for weekend use, it is a nice car to own.

Its no better or no worse than any engine of that period. You can expect no more than 12 to 15 miles per gallon if it has a 2 barrell or less with a 4 barrell. Gas hog? Compared to todays engines that are getting better than 25 miles per gallon, what do you think. Good luck.

I had a four hundred small block chevy (not the unique engine) in my '70 Chevelle for a even as and it were given between 15 and 20 on popular. on the time it replaced into all inventory with a 2 bbl carb and three,08 equipment interior the rear end. that is a drag vehicle now with a huge block so i do not ought to rigidity about gas mileage.

It is a V8 engine. If you translated it in size to the liter system used to measure the engine size of most newer vehicles, a 350 is around a 5.7 liter engine. You can expect to get pretty poor mileage on this one, but it will likely be fast! :)

350 cid=5.7 liter
Not a gas guzzler like a big block, easy to work on unlike todays engines.
They last for YEARS.

Do sheep eat grass. Do bears s--it in the forest.
On the other hand it wasn't as bad as a new smaller V8 with a catalitic converter etc.

that motor is a good engine. If it is stock and in good condition it will be nominal on gas.
However, if it is built to the gills then it will suck fuel like there is no tommorow.
