My 360 build.
The block was not fresh bored. A low mile short block I am rebuilding. Bores super smooth with not enough cross hatch to break the rings in.
Cley
If there any crosshatch there, don't hone it.
Clean the bores until a white lint free cloth doesn't pick up any more black crap. I use ATF on the cloth and clean until the cloth is clean.
When installing the Pistons and rings, use a very small coating of assembly lube (not moly cam lube or something like that...it needs to be a forums latest assembly lube) just on the skirts ONLY. That's all. Nothing on the rings. And don't put anything on the bores after wiping the ATF off.
If you don't have an assembly lube, use engine oil. Again, very little needs to be used. It doesn't need to be dripping off the skirts. Just a little lube.
Then put it together.
By the time it's assembled and ready to fire, the rings will be 95% seated and within a minute or so of running, the rings will be seated.
That's all you need to do.
