Apart from the fact that the A320-214 has CFM56-5B4 or -5B4/P engines and the -216 has CFM56-5B6 engines is there a higher take off weight (77000kgs) for the latter model? Which other 320 variant with CFM engines has a 77000kgs MTOW?

No problem. Apart from that, there never was an A320-100 with IAE engines, so the -131 version doesn't exist. And using the link I provided, you can add data for the A321-212/213.
There's also the A380-842 with the Trent 970B (or so I think).
Some HGW versions of the A345/6 use more powerful engines, the -643 has the Trent 560 and the -542 has the Trent 556.

Based on my read of this, it looks like the last number meaning a certain engine only works within a type (A3XX), not types within the family, which doesn't quite make sense to me. For example, An A340-313 and an A340-213 have exactly the same engine, the CFM56-5C4, whereas an A319-112 and an A320-212 have different engines. Structurally, these two sets of planes are rather analogous (one of each pair is a slight shrink), so why not keep the same engine designation numbers? If I were in a MX team, I would find it much easier to memorize one set of last numbers that correspond to an entire family (e.g. A32X-X33 always has a V2527) than have to get it for each of the different members.
Also, I've read a number of seemingly conflicting things regarding the HGW/non-HGW designations about the A340-500/600. On your site, the A340 500/600 appear to have a consistent designation for engine types, as follows:
A340-X42 (where X can be 5 or 6): T556
I've seen in numerous posts that the HGW variants have an "X" appended to their designation, and that both have the 380 ton MTOW and more powerful engines. Thus, I would expect the entire family to look like this:
A340-541: T553, 372 t MTOW
A340-542X: T556, 380 t MTOW (HGW version)
A340-642: T556, 368 t MTOW
A340-643X: T560, 380 t MTOW (HGW version)
Now, there are plenty of pictures of LH A340-600s in the a.net database, and as far as I can see they're all labeled "A340-642." On LH-taufnamen, the last 10 of them (D-AIHP-D-AIHZ) are listed as A340-642X. Does this mean that LH bought 380 t A340-600s with T556 engines, or is there an inconsistent labeling format? If so, what's the correct one?

the A320 models 211-214-216 231-232-233 can be ordered with any variation of weight variations or engines either CFM56-5B
for the 21X or v2500 for the23X. the highest weight variants were wv7,10,12 77T mgwt, 15 and 17 with 78T
I paged thru the SRM and found NO wv-17's , a few -15's, and a L:OT of 10's 77T, (mostly ordered by UAL and AmWest (now American via USAir).
The Problem with the A320 is the Life limit of 48K Hrs and 37.5K cycles unless the life extension si done for 80K hrs and 48K cycles. This might rule out A320's as freighters in the coming years.
Thanks! Does this same pattern hold true for the A340s as well, where the MTOW and engine combos can be swapped around? IIRC, the T500 is the same engine anyway, and the thrust level is a software issue, do you know if you can buy a 380 ton frame with the weaker engines?

Certainly you can get engines at different ratings, so I assume you can get different MTOW options.
