I’ll have manifolds around mid October 2022, call the shop for info. This is the first run in 4 years … ALL MANIFOLDS HAVE BEEN SPOKEN FOR, PLEASE EMAIL THE SHOP FOR NEXT BATCH.
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 chatter on message boards on how we do it, it’s easy we machine each casting per engine.. Feel free to email or call the shop with questions.
