where to find piston dimension data?

[fostertom]

Any suggestions where to find piston dimension data? i.e. compression height and depth of valve pockets.
Specifically for the different variants of 16v 1386cc Fiat FIRE engine 72mm bore.

Piston manufacturers' printed catalogues used to have briliant dimensioned diagrams for their different pistons but all I can find online is Mahle e.g https://catalog.mahle-aftermarket.com/gb/product.x... and that's only got 2 piston types.

Reason is to pick the best model of secondhand lo-mile 1368 block to get, out of all the 1368 variants, to go under my existing 1242cc 16v head. The only critical thing is valve to piston clearance so I need to find the 1368 data on compression height and depth of valve pockets.

You say 1386...

There are listings with some details for 1368 in this catalogue ?

Page 248 for a Fiat 72.0mm piston. Maybe not specifically a fire engine though ?

Thanks. I previously was baffled by searching the Nural catalogue - now I see it's simple - arranged in bore size order!
