If you are asking if it's a direct swap......that all depends on what engine the car was equipped with. If it was originally equipped with the Pontiac 301 then it's a direct bolt in. Any other engine and it will require changing frame mounts. If it was a Chevy engine in it originally then you'll also need to change transmissions.
I mean, there's no reason why it shouldn't. Its the same rear quarters, and frame am I right? Might need to modify the engine mounts etc, but should fit in no problem, minus the extra hardware...
Direct bolt in....Absolutely not! If you have fab skills, a welder, cutting torch, and various other supplies and equipment you can make just about anything fit into it. Just depends on your skills and how much time, money and effort you want to spend.

No, Pontiac stopped 455 production in 1976. They are easy to swap in though.

350,400 or 455
250
225 / 250 / 270 / 300 horsepower ( 4 versions of the Oldsmobile 455 - 4 barrel carburetor - listed in 1972 )
7100 made
put a bigger carb on it.
First of all....absolutely not an original engine for this year. The last year for the 455 was 1976. Do some research and make sure you are actually getting a 455. The block casting codes are stamped by the distributor and the head casting numbers are on the two center exhaust ports. There are plenty of online sites that will help you decode these numbers.
There were 4 engines available in the Oldsmobile 455 4V, a 225, 250, 270 and 300 HP.
