I did a lot of both street and drag strip running. Back in the 60s I had a highly modified 67 Dodge RT 440CI auto trans.
Among the many mods were a rear end ratio of 4.33 and a Holly 3 barrel carburetor on a Eldebrock high rise manifold and a Mopar experimental cam.. That car did not get mileage it got yardage.
When it was stock it got like 12 highway and 9 in the city if you did not push it too hard. When modified like above it got about 8 on the highway and 4 in the city. Step on it and it got about 1 in the city.
Car was quite fast but even though I worked construction the gas cost was killing me I finely put in a 3.91 rear end and a Holly 3310 carb and it stayed that way for the next two years I owned it. Got married in 1970 and had to get a different car.
