Certainly, this big-inch 1960s V8 engine was fairly thirsty by today's standards, but there weren't a lot of downsides it that I can recall. The 425 Olds was a fairly high compression engine which required premium fuel, and so it might not perform too well on today's unleaded pump gasoline. The horsepower reported in the 1960s up to 1971 was in the so-called "SAE Gross" rating, so it would be difficult to compare this engine with later models which use "SAE Net" rating. A general rule of thumb is that net horsepower is about 75-80 percent of gross horsepower. In case you don't know, the chief difference between this engine and the more common 455 Oldsmobile was the crankshaft. The 425 Olds had a stroke of 3.975 inches, while the later 455 had a stroke of 4.25 inches.
