Hi, I've three kind of pistons

Two first are removed from 205 blocks and the last are removed from a 200 block

Differences between them addition to the visual differences on top of them?
Anyone is better or worst than the others?

Regards

 

hola

The 200 block is from a 4x4 cosworth and the pistons used for these engines had an offset gudgeon pin to help stop "piston slap".

those numbers do not mean anything to me (casting numbers?) but maybe someone on here can help further

 

compression ratio will obviosuly be different on the 4x4 piston to a 2wd, (if the piston is a 4x4 piston?????)
but i don't know of the different casting numbers, need someone who knows their shit
about mahle

 

Wrist/gudgeon pin is offset on 2wd just not as much, don't know about the numbers will check mine from my engine, are by the metal bin, might help a bit ?
