Cool new project, not an A body

Glad to hear you are still saving them, Mike.
A couple of weekends of work and a few bucks for parts, and it will be a driver again.
I would replace all of the core plugs at once if it were me.
It's kind of a pain in the *** to remove the tranny to do the back one, but it will give you peace of mind.

My first B-Body was a '73 Road Runner with a 400 4 speed, so I still have a soft spot in my heart for these cars........
