LS2 Rods which way to install
From a GM manual.
Identify the positioning tab (1) or flat flange (3) of the connecting rod. When properly assembled, the positioning tab or flat flange of the rod and the mark (2) on the top of the piston should both be facing the front of the engine.

Thanks for the help.....The only thing is LS2 rods don't have the flat flange on top of the small end. The only thing that I could tell the difference on each side is one a small tab on the inside of the beam. I'm going to post a pic....
Both sides are chamfered though. I already checked for that. The only thing different for each side is the big end. There is two flat surfaces on each side of the rod but one side is higher then the other and a casting dot on one side of the beam. Other then that the sides are exactly the same.
I should add that one side with the casting dot on the beam has the chamfered side that has the finally machining. The other side is chambered but is as cast. My guess is the side with the casting dot. Would just like confirmation.

I have an 2005 LS6 and a 2010 LS3 sitting in my barn with oilpans off and on both the nipple points toward the rear of the engine. I cant see any other way of telling which side is which...

Check out the pics in Post #6 the "wide tab" on the rod always faces the front of the engine...( The second pic the rod on the left that side faces the front..I.E. the wide tab)....at least that's what I remember from when I assembled mine...My book isn't with me in Iraq though...haha.

Do you see where the cap and rod come together??? Look at the surface area right there...The side with the cast dimple thing on the rod would go away from the front...The surface area right where the rod and cap connect is different it's not the same...Look closer..If I could circle it then I would...hope this helps

Got it to work: Red= Front
Back from a year ago, but I'm having the same troubles and need to get the pistons in the block tomorrow. I"m putting a LS2 rotating assembly in an LQ4 block. Bought the LS2 assembly from a guy and am not sure about how it goes as far as rods. I don't think he took the rods off the pistons but I'm not 100% sure. With all my pistons dots facing forward all the dimples in the rods face the rear. But when installed that will leave one bank of rod bearing locks facing up, and the other bank facing down. Is this correct? My friend that has built numerous older small blocks says that it doesn't make sense that the locks don't face down or are at least the same on both sides. But from my reading here and on other threads through other sites say that as long as the dimples on the pistons face forward and the dimples on the rods face the rear everything is all good. Anyone?
Thanks in advance.
Thanks in advance.
I have a set in front of me that are marked from removing and the piston dot faces forward, rod dimple back, large flat area on caps towards the center of journal, dual tangs (grooves) for rod bearings facing outside edge of block
