Are there connecting rods in Chevy LS1 engines?

We experimented with titanium connecting rods in our Pro Stock engines for a while, but the cost and complexity of titanium were drawbacks. Now Chevy LS1 engines are assembled with titanium rods at the factory, which shows just how radically technology has changed.

Which is the best way to install connecting rods?

Properly installing connecting rods is key to long engine life. Here, we take a look at the different ways to accomplish this task and which works best. There is perhaps no more important component contained in the internal combustion engine than the connecting rod fastener.
