    Hi
    I might get it wrong but at the manual seems there's a 4th pully I don't have on my engine.
    What it is? At the drawing, it doesn't look like the power steering pump...
    And with the side draw (on the left corner) with the 3 pullies it says LG4 engine which is 305 but mine is 350.

    Anyway, I'm looking for new belts. I have 80 Z28 but the engine number is 3956618 which I understood it's from 69' area.
    Can anyone help with the right parts?

    If you're asking about the accessory that's below the alternator on the far passenger side of the engine, that would be the smog pump. A LOT of people leave them off when they replace an engine.

    The alternator, water pump and crank pulley will be in exactly the same place on a 305 or 350.

    I used a bracket set from a 305 on my 350.(no smog pump)

    That number on my alternator belt is: 45013 10A1145.
    (Not sure of the brand.)

    There are quite a few differences. Some cars had Air Conditioning and some didn't. Some cars had smog pumps and some didn't. Some cars had power steering and some didn't. There were also two different belt layouts over the years for the water pump. Some have only a single belt running them, and some have more.
    The belts you need will depend on what accessories the engine has and the layout of the belts across the accessories.

    I know there is no A/C or smog pump but I don't know what exact engine to I have.

    Post a picture of the front of your engine, should clear it up pretty easily.

    The engine shouldn't matter. What will matter is the accessories on the engine and the available pulleys for putting belts on.

    I don't know how you'll figure it by pictures but those are the best I found.
    I don't know if the pulleys are stock or not but I just saw A LOT of different types at Summit Racing by length and width.
