Help please:
I let an 1050 block to bore it for oversized pistons (62.6) The responsible told me that this size, which is stamped on the piston is NOT the piston diameter but the cylinder size to be bored. I have serious doubts about that, because I think it is the piston diameter and some other values stamped on the piston ( i do not remeber exactly what it was, because I let him the pistons too) indicate the cylinder size for this pistons.
I would appreciate any comment, because he is doing that job for many years now and hadn´t any complaint regarding too small cylinder sizes( that´s what he says...and this block is the only one I have...

That person is absolutely correct; the size stamped into the top of the piston is not the actual size of the piston itself, but rather the cylinder size to be bored when using that piston.

Thanks a lot!!
i was really not sure about that. I saw in some german magazine ( Oldtimer Markt, Motor optimieren) that besides of the diameter, there also is stamped the - I don´t know the correct english term- diametral clearance (?) and i thought that this has to be added to the piston size. i misunderstood it then.
i really feel better now...
