Nice! What is the mileage on the car? The V8's had a specific problem where the oil pump would begin to aerate the oil feed as it wore out, causing lifter problems and general bad lubrication. Something to keep an eye out for one you get it running.
The fix is an "Olds oil pump conversion". There's a couple band aid fixes also if you are having minor problems but barely want to drive the car.
You have not mentioned anything on the trans. At the very least you need to drop the pan and inspect it. Most likely it's filled with gunk. The trans should be rebuilt after sitting 50 years. If you barely want to drive the car, you might be able to get away with just changing the fluid, but I can't recommend that. Note there is also a transmission cooler after the radiator which may need recored. Don't just remove it and try to drive.
Unfortunately I suspect the trans will look something like this. Nothing a thorough clean/rebuild can't fix though.
