Has anybody ever seen these types of pistons before? They are inside a 2.0 engine I have and all that I know is they don't resemble the '65 to '67 standard piston as I have a set of those. There is some kind of logo or marking on the crown of the piston and the reliefs are an unusual shape. Sorry I don't have better photos but it was hard to even get photos through the spark plug hole. I suspect they're some kind of performance piston as the engine was rebuilt with S cams, but I really have no idea. Hopefully somebody has seen these before. The silver cylinder in the photos is a flashlight btw. Thanks in advance, DerekName:  Still008.jpg
