Getting ready to assemble rods and pistons for this 390 I'm building and I'm wondering what the consensus is on a typical street build.
Do you guys use a conventional clocking layout? Have one of your own? Determined that it means absolutely nothing?
-
Probably means zilch but....I've always used the conventional thinking as supplied by all the ring makers.
-
I also install the way the ring manufacture directions say. But being that they move around the piston who’s to say the rings don’t line up eventually even if it’s alittle while. It makes you think as long as you separate them long enough for them to break in shouldn’t matter.
-
Have always installed the top ring at 10
Second at 2
First oil ring at 8
Second oil ring at 4

I clock them all the same way each time, just as an assembly "check" for me, but to be honest, they rotate as soon as the engine runs anyway, so I can't see it making any difference at all.
-
+1 Just so they aren't lined up initially. they rotate almost immediately and continue to do so. If they didn't the block would have a vertical groove the width of the ring end gap. I have seen them lined up on tear down on good running engines. At normal running temperatures , piston ring end gap is much less than the cold dimension.

I still like the Dublin Dr. Pepper when I can find it here. It's made with real sugar, not that corn syrup crap. I have been here since '02 and still have to adjust to the way things are done here in Texas at times. :D
