86 Monte- chevy 305 to pontiac 400?

[93transam]

My monte carlo needs rebuilding. My dad has a pontiac 400 at his shop. What do I need to buy to make it fit.

Thanks

Use 301 frame mounts and engine mounts from a G body Grand Prix. You might need to change the trans depending on what it has now, or get an adapter. You should be able to get a 301 engine wiring harness and use it on the 400.
