Is my 340 Overcarbed? Avg 5-6 MPG

Did you put in or use a reproduction fuel pickup? Mine will show empty at only 12 gallons or so. And it will go dry around there too. The pickup is not at the same factory location.

So, how many gallons are actually refilling in the tank?

Have you only driven it 162 miles so far?

How much fun are you having driving around with this new motor?
