re: #228 Decatur Deb
Just a quart—in the SU carbs.
My oldest brother had one when he was in HS. He is eight years older than I am, so I only have my memories of my brother and his friend spending hours trying to keep it running. But it just kept leaking oil on my dad’s driveway (dad loved the drive my brother showed by working on it and never worried about the stain).
