    My 1955 Twin H engines intake has that same casting number.

    Must be for a 55-56 262 as the balance tube is cast in?

    Yes the ballance tube was internal after 54 due to space restrictions in the Nash bodies,

    I forgot to mention my 55 Twin H engine is a 308 with the same intake casting number as your manifold.

    It can be used , as an assembly on any 48-54 stepdown 6 cyl engine ...but a new exhaust pipe and flange will be needed. It has a larger and different angle than the stepdown Twin H. No doubt , the exhaust will flow a little better due to the larger diameter. Whatcha building Kerry? A Hornet powered Hawk? LOL

    Kerry - There were no '55 - '56 262 CI engines. The only big six was the 308 CI

    Come on Dave!! (:

    So this is for a 55-56 308 and I will need a 55-56 exhaust flange to use in a stepdown?
    I was planning to use this on my 53 SuperWasp coupe.

    Kdancy, you will need the headers as above or a complete 55-56 exhaust manifold. The iinterface between the 48-54 intake and exhaust is completely different e.g. 3 vs 4 bolts and size shape of that area

    This manifold is the same as the one that I got from Butch Smith. The manifold is going to go on my 1956 308. Thanks Butch. Walt's garage rebuilt the Carbs. They are beautiful. Dan

    Does the exhaust heating area need to be covered, or can it be open when using headers? Dan

    Mine,(pictured above) came with a cover from the previous owner. Can't imagine why you'd have to have one though unless the heat riser area was so rusted as to leak to the intake.
