With the 400 V8 in a car weighing over 2 tons you should expect very poor fuel milage in the range of 12-17 mpg. The 428 V8 would get even less. Needless to say it is a gas hog.
1in 1967 the 400 cu in V8 becme the standard for Bonneville until 1969, when a 360 hp 428 became the standard Bonneville engine, which in turn was replaced in 1970 by an even larger 455 cu in rated at 370 hp.
about 7-10 miles per gallon
20 mpg going 55 mph
