Buick 364 Nailhead Schiefer 711A Aluminum Flywheel. This was mounted on a 364 nailhead in a project car and never finished. Super good condition and ring gear is near perfect and the clutch disc still has writing on it! Using this lighter flywheel will greatly improve the performance! Also this setup might work on a 401 not a 100% on that.
