160 horsepower - 2 barrel carburetor 180 horsepower - 4 barrel carburetor
I believe about 170 horsepower
I think it s about 230, I know my 1970 has 250 and it s a 350-2 barl.
Low compression, 2bbl carb = 230 hp High compression, 4bbl carb = 290 hp 1964 442 330 engine = 310 hp
Horespower relates to the speed capacity of an engine and thus how fast the vehicle can go. The horsepower of a 1968 Olds 350ci is approximately 350 hp at top speed.

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.
James Olds died in 1976.
