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.

20 mpg going 55 mph
