I’ll have 5 manifolds around mid October 2022,  call the shop for info. This is the first run in 4 years … 

322- 0

364- 0

401- 0

This manifold will fit all three eras of nailheads 264-322, 364 and 401-425. Each manifold will be machined depending on cubic inch. Lots a BS on message boards on how we do it, it’s easy we machine each one per engine.. Feel free to email or call the shop with questions.
