    The NEW 1955 - 1957 Little Birds Forum.

    Squarebirds is very proud to announce the addition of our newest forum, General Technical Discussion - 1955 to 1957 Thunderbirds.

    John G, Ray, and many others have worked very diligently to include Ford's very first Thunderbirds. And frankly, nobody really knows why the '55-'57 Thunderbirds were omitted from

    We will closely monitor this forum for a trial period of time, hoping that it gains tremendous popularity.

    With our addition of Little Birds, comes the first Thunderbird technology such as:

    * 312 cubic inch Y-Block engines (Ford's first overhead valve engine)
    * Paxton superchargers (optional equipment right from the factory in 1957)
    * 1955 Thunderbirds were built with 6-volt, POSITIVE ground electrical systems.
    * 1956 Thunderbirds (and full-size Fords) used 12-volt gauges. 1956 is the ONLY year Ford used 12-volt gauges.

    We are excited to see this forum flourish, so give our newcomers and their classic Little Birds a very warm welcome because that is what is famous for. - Dave Dare

    312 Engine

    Actually, the first overhead valve engine from Ford was the
    239 CID engine that appeared in 1954 full size Fords.It replaced the flat head 239 CID engine. They are not the
    same engine. The OHV 239 evolved into the 272, 292, and then the 312 CID.
