ok all I bought a 6.0 that had the rods and pistons removed. The rod and main caps are in place so that is not a deal but the rods were not marked on the order they came out. I know when i did gen 1 sbc we always marked them before removal. Is this a problem or can they go in to any hole? It will be coming completly apart and checked but dont believe it will need to be over bored.
I hate to drop the cash for a stroker kit right now.
Thanks

Are you using new rings? If not, i would recommend you to atleast dingle berry hone it it and put new rings in it.

 

It doesn't matter. Stick em back in any way you like. Gm did a good job making everything weigh the same..

 

If anything you might want to invest in a new set of rod bearings. Other than that you should be ok.

 

As long as they all weigh the same there isnt a problem.

Make sure the dot drilled in the top of the piston faces the front of the engine.

New rings, rod bearings and a quick bottle brush hone would be advised.

 

All you have to do is make sure the chamferer side of the rod faces the counter weight on each journal. so basicly you put the chamfer facing away from the dot on the piston on rods 2,4,6 and 8 and facing towards the dot on 1,3,5, and 7.

 

great info guys, yes all new bearing and rings will be used. I assumed they could be used in any spot but figured I better check. I will keep u posted. its an lq4 so new pistons may be in order anyway...
Thanks

First what style of rod are do you have? 99-04 LQ4 used a press pin. 05-up LQ4 had a floating wrist pin.

1st picture Shows Press pin rod. Flat squared side of rod always faces forward.
2nd picture shows Floating pin rod. The Larger section of connecting rod always faces forward.

The Generall installed them that way for a reason... I Dont know why, but I dont want to find out the hard way... I have heard they can be flipped but again I personally followed the factory recomendation on my engine.

As mentioned Dots on pistion always face forward.

Good luck on your rebuild!!!

 

more great info, I was not sure what year the motor is but believe it is an 03 but will check to see what rod it has. And I agree i will do my best to put it back together the way it was intended.

 

Cool build man, best of luck getting it all sorted out.
