    Default 2F gearbox on a 4.5 EFI

    Hi Gents

    I want to know if a 2F gearbox/bellhousing will fit on either a 3F or a 4.5 EFI motor without a adaptorplate?

    Thanks

    Dirk

    It should fit the 3F, since the 3F's 5 speed gearbox fits onto the 2F.

    The 2F had the H42 4 speed box. The H55 were a 5 speed version of the H42. Correct me if I am wrong but the 4.5EFI only came with the H150.
    It is not what you buy its what you build.

    I'm sure you are right. It might fit though, since there is a lot of backward compatibility with the older cruisers.
    I'm not sure it would make sense however, since the H42 gearbox might not be able to deal with the torque of the more powerful 4.5 engine.

    The H42 is a truck gearbox on the lines of the famous American NP435. The guys run v8 through them. Only problem in high torque conditions is the aluminium transfer case working it lose from the cast iron gearbox.
