    Tonawanda is a plant that built a lot of the engines in the 60s-early 70s. I think it is in Michigan, but Im not sure.

    They are still producing engines there; GM has invested $825 million since 2010 at Tonawanda for the engines it builds, $400 million of that specifically for the Gen V small block.

    There is no difference. The 454 is the size of the engine. Tonawanda is the location they were built. I don't have a complete list of GM plants that built 454s, but likely Flint built some too.
    When multiple plants built the same engine size, they used the same molds, so the engines were the same.

    Ford did it different. No parts interchanged between engines from different plants, and even Ford doesn't know why they did that.

    I could be mistaken, but I think the big block crate engines that GM sells are still built in the Tonawanda plant. Old school small blocks... Mexico.
