I can believe that. When I was 16 my mom had a 73 Olds Custom Cruiser station wagon with a 454 engine. It literally got maybe 5 mph.
It was literally 1/4 tank to get to school and back.
5 MPH ???
OR 5 MPG?
I have a 1976 1 ton Chevy dually truck, and when hauling 4 horse trailer.....5 MPG + is about what I get. I have 2 opposite side fuel tanks, 20 gallons each. I NEVER plan on more than about 180 miles between stops, and I ALWAYS carry extra fuel. I have had that truck since April 1984, and have put over 250,000 miles on it myself, mostly hauling hoses,
mostly alone.
we had a 1970 chev kingswood wagon with the 454....wide open throttle seemed you could see the gas guage dropping!!!
