Identifying JE Pistons
 

I am considering buying a set of low mile used JE pistons that we believe are #274048 but they are unmarked and do not have the original packaging or paperwork to verify.

The site lists some dimensions which I can verify on the parts themselves and can compare with my existing pistons but how would I go about verifying their compression ratio? My engine is currently torn down so I cant do any kind of dry fit at TDC to check.

Thanks in advance.

I just found JE offers a reverse engineering service to ID their pistons.

I think Ill go this route instead.

Thanks.
