This manifold will fit all three eras of nailheads 264-322, 364 and 401-425. Each manifold will be machined depending on cubic inch of engine. Currently we only have 2 for the 401-425 engine. We are unsure if we will cast more in the future.
Feel free to email or call the shop with questions.
Cast in American off patterns we own, and paid for!!
