spam: [W126 Coupe] 380 to 500 euro conversion

[Faber Castell]

The 380 US is 155 hp, 380 Euro is 204 hp.  stock.

Euro models NEVER used single chain... it was a US "Special".

Another interesting point FYI, European models had ABS from 1981 (and 
before)... so your "parts car" will have the brake system too.

The 560 US is 235hp, 500 Euro is 230hp.  stock.

The 560 ends at 1991.  Why bother going to that trouble?  You're on the 
right track with the 500 Euro conversion.
