Just curious as the 767 and A330 have roughly the same size cargo door opening on the lower hold, but is there a difference (and if so what is it) between the height once in the lower lobe? Thinking along the lines of the underfloor lavs on LH birds...

There is minimal difference in height between the cargo holds of the B767 & A330/A340. Within a couple of inches. Both are designed to hold containers with a height of 64in, plus around 3-4 inches space above the containers. It can also be variable within an inch or so depending on where in the cargo hold you measure.

No they don't have the same cargo hold door sizes...

The A330 has a forward door width of 106 inches and and aft door width of 109 inches. Cargo hold height from ball mat to ceiling is 66 inches.

The 767 has a 134 inch wide door or 70 inch wide door depending on the model. ER models have the larger forward door. All aft doors of passenger models are 70 inches while the freighter has 134 inch doors forward and aft. Cargo hold height is the same as the A330 at 66 inches.

The difference is the loadable width of the cargo holds. The 767 has floor width of 96 inches and full width container loadability of 125 inches while the A330 has a floor width of 125 inches and full width container loadability of 160 inches. The A330 hold contour is standard double LD3 size as is the case for many other widebody jets including the 777, A300/A310, DC-10/MD-11, L-1011, and the A380 (Unitized compartments 1,2,4, and 5 only) The 767 and 747 are the oddballs, the 767 having a unique double LD2 contour and the 747 having a double LD1 contour with the largest loadable width of all at 186 inches.

Lower deck cargo holds of widebody aircraft are basically standardized at 66 inches in height accommodating standardized aircraft lower hold ULDs, which for the most part are standardized at 64 inches in height. The notable exception being the LD3-45/46 made for the A320 aircraft that is 45 inches high and built on a standard "K" base pallet, dimensions 61.5 X 60.4 inches.

Hope that information helps.
