Vaquero Posted August 22, 2014 Report Share Posted August 22, 2014 Long story short I bought an LQ4 out of a 3/4 ton and am rebuilding it using LQ9 rods and pistons to replace the motor in my SS. My question is about the orientation of the connecting rods. I already know how the pistons are to be orientated. They have a front mark on them. But the connecting rods don't have a "rounded" side and a flat side. Both sides are machined flat. I have the GM service manual for the LQ4/LQ9 and it shows them having one rounded side. This is the only way that they show orientation. If anyone has any input or ideas I'd appreciate it. Also if it makes a difference they are GKN rods that are stock replacements for the LQ9.

asund24 Posted August 23, 2014 Report Share Posted August 23, 2014 If you can try to get a set of LS3 rods, much stronger. Also found this pic on LS1 tech Quote Link to comment Share on other sites More sharing options...
Vaquero Posted August 23, 2014 Author Report Share Posted August 23, 2014 Thanks for the reply. I'm not planning on doing anything crazy with this one. I'm just building it back as close to stock LQ9 specs as I can. I just need to know what the orientation of the rods should be. Here are some pics of one of the rods.

12'SROCK Posted August 24, 2014 Report Share Posted August 24, 2014 I put mine with the dimple facing the counter wights of the crank shaft. There are many people who run them either way and haven't had any issues. Quote Link to comment Share on other sites More sharing options...
Vaquero Posted August 25, 2014 Author Report Share Posted August 25, 2014 Thanks man. I researched for quite a while and got very mixed results. So all of the dimples on mine are facing the rear of the engine. Lol Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
