New-to-me ‘78 Grand Maquis
 

Hi all -
I just picked up a nice ‘78 Grand Marquis. Whiten exterior and red leather interior. I’ve always been a GM guy so this is my first classic Ford. What is there to know about the 400 block? Reliable? Resilient? It is merely a daily cruiser and not looking to mod it for performance. Anything to check and to note? Any common issues? Thanks!
