Connecting rod position Long story short.. Im ready to put the rods and pistons in the motor.. Im really doubting that the machinist put them together right. He blabs about the offset of the rod and yadda yadda..
For i guess simple terms there is a "square side" and a "rounded side" to the rod.. Which side goes towards the other rod or towards the crank.
I have my opinion but i want someone else to either confirm or deny it.
Thanks

It depends.
Usually you want the chamferred side, or I guess the "rounded" side to face the cheek of the crank. This is mainly so that crankshafts with a radius on the journals won't bind on the bearing and give you a clearance area instead.
However, OEM LSx cranks have an undercut fillet, so it doesn't really matter as long as the pistons are oriented so that the dots face the front of the engine.

Here is a decent explanation for the piston side of things. CLICK HERE
