Daily Driver.. LA318 vs 360 Magnum

Back in 1977? I had a 75 360 Cordova with a 360 2.76 gears. It was easy 20 mph on the highway (80-85) but too not great in the city. I did was remove the Lean Burn and re-jet the carb. One day a gentleman came into the station and remarked on the paint job (custom) and asked if it was a 318 and I told him 318's were pigs, remember 1977, so I told him about the millage and the torque and he said no way so I thru him the keys and when he came back he said from now on I'm only ordering 360's in all the ones I order. He ended up owning a Chrysler dealership!
