Piston Identification
« on: 05.04. 2010 05:43 »
Can anyone help with identifying these Pistons, ie manufacturer and compression ratio. Inside markings are 3568 AM 413 and AE 11412. On the crown are +040 and I.D.10. I know that they are 40thou over A10 and they came out of a road rocket, but I would like to know the compression ratio before I reassemble the motor. They also each had a dob of green paint under the crown.
Regards
