1971 OLDS 350 : - 2bbl =240 hp -4bbl = 260 hp - W-30 = 290 WHILE THESE #'s MAY SEEN LOW, KEEP IN MIND THAT THESE ARE SMOG ERA ENGINES. ALSO : THE OLDS MOTORS HAVE MORE TORQUE PER CUBIC INCH THAN OTHER MANUFACTURER EXCEPT THE MIGHTY Buick. FOR THE STREET, TORQUE IS WHAT WINS STOP LIGHT DRAGS AND MAKES A STREET CAR FUN.....I OWN A 71 WHICH IS MY DAILY DRIVER AND I'VE TAKEN OUT MANY A MUSTANG AND CAMARO WITH COMPARABLE HP.
Absolutely NOT!! While they do have the same displacement, they are COMPLETELY different engines.
I believe about 170 horsepower
380 Factory Horsepower

160 horsepower - 2 barrel carburetor 180 horsepower - 4 barrel carburetor

Buick, Olds, Pontiac, and Cadillac had the same bolt pattern. Chevrolet is different.
speed wise the Chevy engines are better but build for strength wise the olds wins.
The the 1969 OLDS 98 had 365HP
1977-80 Olds 350
Chiltons manual says 170 horsepower and 275 ft.-lbs. of torque.
From 1982 - 1990 all of them came with 4bbl carbs rated at best a pitiful 140 hp and 255 lbs of torque - These engines are externally identical to an Olds 350 and are easily and commonly swapped out for the pre 1974 Olds 350 with the higher nickel content and the better heads which are rated at around 180 hp - 200 hp, stay away from 1977 and later engines.
AnswerALL are 4(barrel carbs) NO 2 BARRELS. horsepower ratings between 140 and 180.VIN Y 140 NON ROLLER Any olds except 442VIN 9 180 WITH ROLLER CAM ONLY85-87 OLDS 442
Chevy Cavalier or Olds Calais...
225 / 250 / 270 / 300 horsepower ( 4 versions of the Oldsmobile 455 - 4 barrel carburetor - listed in 1972 )

No, the blocks are different.

only if the trans is from an olds, Buick or Pontiac engine. The bell housing bolt pattern from these engines is different from a chev block

A 350 Oldsmobile engine has a different bolt pattern than the Chevrolet engine. The 350 Olds and 350 Pontiac engines have the same bolt pattern. The 350 Chevrolet and the 350 Buick engines have the same bolt pattern. Unless you have a dual bolt pattern transmission (there are some out there) in that Chevy, the Olds engine won't bolt into the Chevy transmission.
Varies depending on year engine was built, as well as compression ratio. The most powerful factory 455 was installed in the 1970 Toronado (W30?) and is quite rare--that engine is rated at 400 hp--455 Olds engines installed in vehicles with the Police Apprehender Pursuit package (exceedingly rare) were rated at 390 hp--Be advised that these engines were all produced prior to 1972 when compression ratios dropped, and were rated at the flywheel. 1972 and later engines were "SAE net" hp--measured at rear of transmission with ALL accessories (power steering, alternator, A/C operating.These engines excelled at torque output rather than horsepower due to their undersquare bore and stroke configuration--that is--their stroke is longer then their bore.
