Does any one know what size rings are required for the stock forged piston for 5.0? My piston have a E7 part number on them. I do not know the complete part number at the current time. I can give this after I get home from work.
Not sure what you mean by size?there stock you have to file them to the ring gap.
I'm talking about thickness. There are a couple different sizes. I probably have to measure the ring grooves or the old rings. I have to get a battery for my digital calipers. Just thought someone may know.
the H.O forged pistons use the metric ringset.
I have measured the old rings and came up with 1.5mm, 1.5.., and 4mm. The piston part number is E7ZE-6110-CA.
