    Default Engine, gearbox identification

    after having a better look at the engine and gearbox that came with my project 240z here are the numbers. Any info is great
    engine no. L28-451267
    gearbox nr. (stamped on top of bell housing?) 7419704
    cylinder head has acasting nr. on the side - N42

    go on.. tell me it's a special edition 50000hp beast or just the truth will be fine

    The numbers look like those of the common 2.8 liter engine used in the 280Z. My 1976 L28 block, with N42 head, has number 071155 stamped on it so your block is newer than 1976. In the states, they started using the N47 head in late 1977, but maybe the N42 was used outside the states. Where do you think the engine came from, Japan, US or Europe?

    it's difficult for me to tell were the engine is from. It would have originally been an L24 then it's been changed by the previous, previous owner before 1986

    L28+ 280Z block, N42= 280Z head. If you have a 5 speed, its 280Z. There were no special option motors that you could order from the factory. There were very few option that could be ordered, air, auto, the color. That was about it. What you have is a 240Z with a replaced 280Z motor and trans. Pretty much the standard replacement stuff on a 240Z.
