Hej community !

I have a stock C10 Burb with a 350 engine and auto (not sure which version) from 82 rather new edelbrock carb fitted and runs well, what type of mpg should this set up be expected ?
Recently did a trip from mid of Sweden (Gothenburg area) down to the Nederland approx. 1200 km (745 miles ish) one way mostly freeways and "normal" roads, i sort of end up at 1,6 - 1,7 L/km (13-14 mpg) would that consider to be "normal" ?.

And of course the tread shall consist of pics :)

That doesnt seem bad for a carbed 350
Being an 82 i guess it could be a 3 speed th350 automatic, or a 700r4 (4 speed automatic)... if its stock

With the current tire size, i'd expect a little better than 13-14 though

Whether its a 3 speed or a 4 speed automatic will really determine your expected MPG though bottom line.

With a 4 speed automatic i'd expect better than 13-14.

With a 3 speed automatic thats reasonable

I would say that's about as good as you'll ever see. My '85 (305, T350, 2.73 rear gear) got 12 on the highway, 12 in the city, 12 uphill, 12 downhill, 12 sitting in the driveway, 12. But it had 2 cylinders down on compression. I have a few friends that have seen as good as 14-15 with a healthier 305 or 350 and a 700R4.
