Hey Guys,
I have been rebuilding an RT1 360 for a while now and I am at the point of replacing the piston and rings. The cylinder wall looks good so I just want to put the same size piston and rings in but I am having trouble identifying the size of the piston. On the top of the piston, next to the arrow it has a #75 stamped in it. Opposite of that is #8025. Can anyone tell me if this is a standard (stock) piston or is it an oversized piston. Thanks!!!
