Mark,
if the AM2 engine has a red label, that would put it in the 1980s.
Has it got a light flywheel/diaphragm clutch, metal cowls or 'recycled tyre' cowls?

The engine numbers for the AO6/635 engines suggest 1983 & 1987, but don't forget how
easy it is for someone to swap plates over, with only a couple of pop rivets to slow things
down.

Btw, I never take it for granted that an engine will have the same pistons as when it left the
factory, given how few folk seem to know how to set the timing correctly.
One independent I knew melted a set of pistons on his own 2CV, refused to accept that he
might not be doing things right and did the same to the replacement set of pistons and
barrels within 6 months.
He didn't stay in the 2CV servicing business for very long... :roll:

Thank You Ken

So the AM2 / 048 2 010 921 gives me an M28 from a Dyane6 or an Ami8, with 9.0:1 pistons and 35hp :?: What might the year be: 1972 or '82?

I do also have a pair of red labelled engines:
A 06 / 635 with 090 3 054 288
A 06 / 635 with 090 7 015 496

Are these 1983 and '87 respectively, and both M28/1 (2CV6/Mehari) 8.5:1 compression and 29hp :?:

The AM label is properly stamped throughout, like the black one above, whereas the A 06 labels are semi-printed

No, those engines are in the garage, not the van...

Thanks for the reply and the tips ;) I've no idea about the ancillaries - they're all under a tarp at the back of the garage, awaiting a springtime investigation...
