    Hi,
    Don't know if this is the right forum, feel free to move.
    I am looking to find the dimensions of the 3.0l (250)version of the Colombo v12 and was wondering did the actual block change in the subsequent 275 and 330 iterations or was it the same block but bored out?.
    thanks

    The blocks did evolve through 250-412, but share similar exterior dimensions, although the heads did grow in size on 4 cam versions.

    Things like headbolt size, quantity and placement changed, coolant passages, oil ports, etc have changed.

    The accessories, alternators,water pumps, oil pumps, timing cover, smog pumps, a/c compressors, etc. vary widely from model to model and even year to year

    What dimensions are you looking for specifically? I have several 250-365 engines I can measure. Or if you're looking for more general interchange, check some of the parts suppliers for catalog information.

    250 engines have 4 engine mountings along with the early 275 and 330 engines. Later 275 (not 275 GTS or 275 GTB/C) and 330 engines from 1966 on are 2 mount.

    I'm assuming he's looking for bore and stroke(?).

    please specify what exactly you need to know?
    dimensions over all?
    weight?
    bore and stroke?
    diameter main baering/rod bearing?
    torque for those?
    also you need from the heads? you only mention engine dimensions.
    a little more specifying would be great

    also would be great if you fill out your profile and introduce yourself a little before asking here

    Hi,
    Thanks, my apologies for not being more specific in asking the question. What I am interested in is the exterior dimensions with and without ancillaries of a Tipo 168 engine.

    I don't have a 168, but 128 should be fairly close depending on what exactly you're doing

    Rough block measurements
    Width of valve covers
    Length Water pump to bellhousing flange
    Height oil pan to top of carburetor without filter or velocity stacks
    18"x35"x25" - 460x890x640mm

    I don't have any 168 accessories, sorry
