    Hi All,

    Sorry if the title isn't worded correctly. I'm wondering if anyone can give me some tips or advice on how to determine if the engine in my 72 Dart is the original powerplant that came with the car itself. I've read somewhere things like, look at the left side of the block and whatnot... but I am needing an "Explain it to me like I'm in 5th grade" kind of guidance LOL

        Matching numbers means the numbers stamped on the engine block usually above the oil pan, numbers stamped in the radiator support, number stamped under the trunk seal, and the VIN tag are all the same...

          Maybe someone with a slant 6 will be able to tell him exactly where the VIN is stamped on the block. Which is the question I believe.

            from the internet "Slant 6 Forum"
            "on a slant six you should have a pad of metal below the #1 spark plug where the cylinder head meets the block (the pad is actually an extension of the block deck...it will have some information pertinent to your engine (note if the block was rebuilt in the past and heavily decked the pad will be blank).

            Also near the back of the engine on the passenger side near the pan rail there will be another pad (may need to get some rags and brake clean to read it), this should have the last numbers of the Car's VIN that the engine was assigned).
