Pontiac produced 400's through 1979, so if the part you heard about the engine year is true, you can still do it. Years ago I was able to pass the idle test with my mildly modified 400, so I know it can be done. If you retain all of the emission devices, you'll have a nice street machine that can pass the idle test.
As far as 80's options, it gets more complicated. 80's GM vehicles were corporate powered, meaning Chevy powered. Nothing from your Pontiac 301 will bolt up to a Chevy engine, so you would have a lot more work to do if you went this way.
