Stacey Posted June 25, 2020 Report Share Posted June 25, 2020 With the chevy 305 capable of mid 20's per gallon useage and a tank size of about 20 gallons I guess 425 miles. Link to comment Share on other sites More sharing options...

Good thought, however 425 is not the answer. HINT....Fuel tank capacity is 25 gallons! Anyone else want to try? Link to comment Share on other sites More sharing options...

Anyone else want to try? I drove my 1987 Avanti to South Bend, 750 miles one way. I do not remember it as being particularly good on mileage. The answer that you are looking for is probably 4)600.
