Yes they are although the dry sump oiling system had more capacity in the later years. The 2013 model year had lead free bearings also

So they are not solid titanium. What advantage does a titanimum plated connecting rod have? Reducing friction with the crankshaft journal? Is this a common problem? The reason I ask is that I am considering buying a Z06 with an engine that needs rebuilding.

The rods are solid titanium. They are coated with something that improves abrasion resistance. The advantage of titanium connecting rods is light weight. While being light, they are also stronger than aluminum. This helps the LS7 achieve 7,000 RPM.

Personally, I think this is a good place to be in as long as you can purchase the car for a reasonable price considering it needs thousands of dollars worth of engine work. Just don’t rebuild it with OEM components. Personally, I would use aftermarket heads, rods, etc. The engine can be rebuilt to be fast, strong, and dependable. It won’t be cheap if it’s done right, but let me tell you.......the Horsepower, but especially the low-end torque is absolutely intoxicating.

The rods are not “solid titanium”. They are a forged titanium alloy (mixture of titanium and aluminum + others) and are quite strong for their dimensions. Their purpose is to reduce rotating mass to allow higher rpm for the long stroke. They do need to be coated to prevent gauling between rods. This coating will not degrade in a properly assembled and
lubricated engine. Rods can be recoated if needed and recoating saves money compared to replacement.

Huh, that's strange. I'm the original owner of a 2011 Z06/Z07 and I'm still doing track days with the original valve train. In fact, with the exception of the seats and the addition of safety harness, the whole car is original.
