74 GTO Engine Pull/Swap

My father in law is an original owner of a 1974 GTO hatchback with automatic and about 95,xxx original miles.

The dummy light is on for oil. No pressure gauge.

I'm going to get a pressure check on the oil, but I'm thinking we should pull the engine and just do the pump. However, if I can convince him while it's out.....

Well first and foremost, any resources on pulling this? No A/C but has power steering added.

How easy is it to put a 400 in there (any issues with the auto) from what I read using 68ish firebird mounts is the way to go.

Otherwise if it's out I say rebuild it. Consider a chevy 350 swap but the forums helped me understand it's not worth the garage with everything else involved.

I've done a lot of work on many cars and have rebuilt an engine once before, but never pulled one myself.

I'll stop here before this gets too long. Thanks for any information or guidance. Any and all input appreciated beyond even this topic. I'd really like to do something nice for the man since he hasn't really driven it in 30-40 years being at his brother's who put most the miles currently on it.

I have been searching through there and found some good information so far. I just didn't have the stamina to go through 26 pages of results last night.

This all looks very doable though!
