First you need to check your state's smog laws. Most states will require you to keep an engine that your vehicle was available from the factory with. Some states allow that requirement to fall away after 30 years.

Next, to list everything that would need to be done would take an hour or so. Basically, you'll need to remove the motor. Remove the ignition system and electronic controls. Then you'll need to swap those over to what the stroker engine has.

The trans should work. The gauges should work as long as you have the proper sending units. You may need to change the transmission crossmember and center mount.

You could check hot rodder forums. You could pick up a Haynes manual:
http://www.2carpros.com/articles/mitchell1eautorepair-car-repair-manuals

The manual is going to be your best bet. It'll have everything you need listed. But there really isn't a 'checklist' for pulling the stock motor and installing an older one. You're going to need to know the year of the car the older engine came out of, so you can find what equipment and components it needs to run.
