How to Identify Proper Piston and Rod Orientation. LS3 3rd Gen Camaro Project$ 

Thanks for sharing rod to piston install .I been looking all day on the web for l.s. 3 now I know thanks. I gonna put my l q 9 altogether with confidence.peace gear head.lol.

Nice bro..... thanks..almost 10 yrs i fot the correct ppsesion but when i see your vedio..now i remember..god blz

Hello from Germany ! I am allways install the cam shaft first ! :-)

thank you im gapping my rings and your info helped me out

I no longer feel alone for having and using fishing pliers in my tool box lol

you should start a forum thread on thirdgen.org and link your videos there might help get some views. good video dood

The chamfered side of the rod goes to the crank fillet so 1 3 5 7 the dimple faces forward and 2 4 6 8 the dimple faces back the back of the I always was told.

To the ones who say one bank goes one way and one goes the opposite - I just tore down my 2007 - gen 4 engine with 365000 miles on it. I have this Tahoe since new - so it has never been tore down. EVERY dimple is facing rear! There is zero wear on any bearing, and there is .015 side clearance. And I've tore down 7 more gen 4 LS engines (cannot say if they were never tore down) but EVERY one had the dimple facing rear. So, for 1, 365000 mile LS, and 7 more LS's, the factory installed the rods wrong? UM, NO. When a stock crank is used, the dimple can be used for orientation. When a crank with a radiused fillet is used - you should be using proper rods with proper chamfers...

hey iroc, i was wondering where those pistons come from i just bought a set of used 4th gen rods with those pistons on them and i cant find where they came from !

That means , every connecting rod have a mark to find out the direction?

How much does each piston weigh? If you don’t know this, then you are setting your engine up incorrectly and its pretty much guaranteed to be unbalanced. There’s alot more to proper assembly than you can get from a guide or from reading a book. I have assembled hundreds of(if not, over 1000) engines and have learned the hard way more times than I’d like to admit. The most crucial focal point on any LS engine oiling. Biggest effect on even oil distribution is the rod bearing and main bearing clearances. Installing the cam bearings correctly too.. honing and polishing the journals is a must. And then plasti-gage the clearances within spec... people recommend hi pressure oil pumps as a bandaid for sloppy engine builds. Take your time and do it right the first time... And You won’t end up doing the same thing again next winter.

Could you post where you got those spec sheets?

What brand of piston
