Hi
Y block 272 has taken out a piston as I will change all piston rings.
Question 1
Piston is a Fomoco ECB 6110A i think it is standard size but i can't find any info about this piston anyone here who has info on ECB 6110A?
I have parts catalog from 1956 after that piston should be B5A 6108-A
Question 2
I have bought sealed power 5155x at Rock Auto it is standard size and should fit but topring is not the same the old one is like photo 2 the new one is like photo 1 sharp
someone here who has used sealed power 5155x with sharp top ring?

Just make sure the piston ring grooves are clean of carbon, and install the new rings like the instructions state to.

ECB 6110-A is the ENGINEERING PN
B5A 6108-A is the SERVICE PN
You will need an OSI MANUAL to convert.

The various ring manufacturers do have different engineering in their rings so just follow their specific instructions. Just be sure that top rings go into top grooves and if so marked, orientated properly in the piston grooves in regards to ‘TOP’.

another thing you will find is most aftermarket pistons will be down as much as .020 more in the hole than ford pistons
