forged piston size

[turbojim]

hi guys
as the title says im looking for help on finding out the size of a set of je forged pistons i have
i think they are 74.75mm due to the fact underneath the piston say the underside of the piston top the is je on one side and 30 on the other

im guessing that means they are 30thou oversized which is .75mm

but can anyone shed any light as to if this is true??

thank you

could you measure them with some sort of calipers

 

[turbojim]

tried that but now sure if its the correct way to do it

Measure it with a micrometer mate. Don't think they done .75, i've only ever seen .50 and 75mm oversize.

Mesure them with a caliper or a micrometer just below the piston pin.
