Hey guys. i have a question. i’m building an LQ9 and i know when you put the rods on the crank it’s supposed to be (chamfered)(flat)(flat)(chamfered) but these rods that i purchased are chamfered on both sides(part number CRS6100M3D) so I’m assuming they’re omni-directional? The engine isn’t in the car yet so if i need to dig in and flip them i can. Any help would be great! thanks!
in both of these pictures you can see there’s no definitive marking or step out like how there is on stock rods where it’s clearly a flat side and a chamfered side. these are identical on both sides so i just put them in with the logo facing the front of the block on all the pistons for OCD reasons.
the way i placed them in the block i put all the logos toward the front. just so happens that that means on one side of the block the rods have the oil pin facing up, the other side are facing down.
As KCS said, with a stock crank it doesn’t matter. The Oem cranks have no radius to the journals.
mayBE with these particular rods that may be true but with summit rods, that isnt true. I put one in the wrong way and the engine did not turn....stock crank.

That was probably a different problem than what we're talking about.

so i should be fine? it turns over smooth as silk. i have a pretty good knowledge but this is my first engine build and i have 3 grand on the line with this so i just wanna double check everything. thanks!

Silk screened lot numbers on the rod and cap towards pan rail. The fillet on the stock crank rod journal is almost non existent but I’d still install them with the larger bevel towards the fillet.

I called Eagle. They clarified that there is a larger bevel on one side, but it’s not much larger. i’m gonna have to take it apart and flip them. while i’m in there i’m gonna lathe the dome off my piston. I calculated a 11.7:1 CR and i’m just not comfortable with that. my new CR should be 10.9:1 which i’m more comfortable with. I appreciate your response!
