    I could tell you if I had the part numbers that should be cast into them.

    Drivers side looks right, passenger side does not. What are the casting numbers?

    All big block Dart manifolds are not the same, just something to keep in mind. The 67, 68 and 69 are all different with the 69 manifolds flowing the best. If your car is an original 69 440 car, you will certainly want the 69 manifolds.

    They are all similar in appearance.....but to me, the passenger's side looks right for a big block A body. Whether they are correct for a 69 only the casting numbers and date codes can determine.

    I stand corrected on the passenger's side. After some quick research, it is not correct for the 69 M code cars. It could still be for a big block A body possibly, just not the 69 M code. The outlet would be longer.

    They do look correct as the driver side needs an extreme pinch for the steering as yours do, 600 is a steal. Now that I read that all B/RB A manifolds are all different, you would want the right ones. Expect to pay like $4K for the 440 ones. Thats nuts.

    Warning: Accurate LTD repops a modded 383-Abody manifold, yours look too good to be true OEM.

    Driver's side is 383 a body, not sure of year without casting number...passenger side is not a body, outlet too short.

    They are definitely NOT 440 A-body ("M"-code)

    Casting numbers will answer the question.

    agreed the left is big block "a" year and cid unknown, right side is an B-body HP manifold. perhaps milled to properly fit an a-body but not technically an a-body manifold. Either way still a decent deal, even better if proper head pipes are included.

    Correct right side manifold is casting number 2863900 this is for all big block (non-Hemi) a-bodies either 383 or 440 all use same right side.
    Left side 67 - 2899002 (383)
    Left side 68-9 - 2946729 (383)
    Left 69 440 - 3462017

    The Accurate left exhaust manifold is clearly fabricated from a b- or c-body HP manifold and not factory. I don't think they are even making it anymore.

    I run headers. but was just wondering, have any of you guys ever ported or opened up any stock type exhaust manifolds? think one of our engine gurus around here did it on his dart.--??:coffee2:

    depends on where you stand
    if your standing in front of the car the drivers side is the right one
    the passenger side is the left



    :D

    sorry, I couldn't resist
