Hi all,

Just found the below in the garage, i bought them a few years ago but have never had the chance to use them and to be honest i wouldn't know where to begin!!! Do they still get used at all? are they worth selling or should i just bin them??

Cheers

Olly

well they look new, but can't say i've ever seen an A-series piston with a lip on like that before. Where they bought for the A-series engine?? Do they have any numbers on them to identify exactly what they are??

Thanks Ryan, i'm pretty sure they have been used before, i believe they are from one of the early coopers but not really sure, the raised section allows a high compression ratio.

Numbers on them are:

M2050/3 MOWOG

Best pistons for use with a big-chamber 12G295 head.
All engines with this partikular head had D-top pistons.
(I don't know about the Innocenti 850 engines, but propably no)

What size are they? If they'r any overbore-size they'r worth quite a bit.
Overbore D-top pistons are getting rare!

Put them on eBay, if you want to get rid of them.
I think you could get a bit for them, if standart size.

Cheers,
Jan
