The Dry Sump Lubrication System has been around now for several years as a standard option on the Corvette Z06 and the ZR1. But the with release of the 2010 Corvette Grand Sport, its the first that the system has been installed on the base LS3 engine. GM Assistant Chief Engineer for Small-Block Passenger Car Engines John Rydzweski gives us a tour of LS3’s dry sump system and we learn some interesting tidbits including where these engines are assembled.
As we’ve discussed previously, the Corvette Grand Sport program replaces the popular Z51 Performance package. With the manual Coupe version, Chevy takes the performance of the LS3 to a new level with the addition of the dry sump oil lubrication system. The system minimizes oil starvation during hard cornering.
A little know fact is that these dry-sump LS3 engines are assembled by hand alongside the LS7 and LS9 engines at the Performance Build Center at Wixom. Just like the Z06 and ZR1 power plants, these engines contain a badge with the builder’s name. They also go through the same quality tests before being shipped to Bowling Green.
Want an LS3 with the dry sump package? You’ll only find it on the 2010 Corvette Grand Sport Coupe equipped with a manual 6-speed transmission.
