    Is this a trick question? :)

    Looks like a mechanical 465 bellhousing to me.

    No trick question, just never seen a 465 fully enclosed bellhousing before

    Aren't they all? Auto trans angled, typically thick AL cover, 465's thin sheet metal flat piece, gasket around the starter nose.

    Look at the difference between the one up top and this one, there is no fully enclosed bottom on this one around the bottom of the bell

    All the hydraulic (later) ones are fully enclosed, the open I expect is OLD.

    So the one at the TOP would be a hydraulic bellhousing?

    Anyone else have any comments?

    Yeah i know that, but the one up top is and that is the one I'm trying to figure out cause I don't need it. Want to sell it but have no idea for what 465 its for.

    Tazz, the upper one is the one off of the burban I gave you. it's off of a sm420 and has the lower half. Also the starter bolts on to the bellhousing and not the block like the later 465 version. All 465's I'v seen are fully enclosed and made of aluminum.

    The first pic you showed is exactly like the one on my truck (still the stock one).

    I think it's all been sorted out, but just in case, the first bellhousing is not hydraulic. It's mechanical. Hydraulic would have the ear for the slave cylinder cast as part of the bellhousing.

    I'd call that a 73-81 bellhousing or thereabouts.... since it doesn't have the extra holes that are used with the 4spd side-loader (OD) transmission ;)

    Same bell housing I have in my driveway waiting for my new engine to be delivered. It is off my 1984 K20 with 350HD and 4 speed trans and NP208 transfercase. I can send a picture if needed to validate
