For the first time at a Museum event, the Museum was pleased to welcome Jordan Lee, the Chief Engineer of Small Block Engines, to present.
Jordan mentions that there are three main objectives that they have to consider with the new LT2 engine. Those things are performance, enhanced track capability, and the new mid-engine architecture. With performance, it’s about improving the legendary LT1 engine capability for Horsepower and Torque; for enhanced track capability, it’s about meeting aggressive handling targets from the beginning and significant engine engineering, and the new mid-engine positions and design considerations are components for the new architecture.
Several things are new with the LT2 exhaust manifold in the mid-engine Corvette. From the four-into-one twisted header design, upswept runners to empower mid-engine layout, and now fabricated instead of cast to help with mass savings, and more, all created significant engineering challenges that need to be optimized for all considerations. Jordan mentions that there are also several benefits because of this new manifold, like sound quality, and even recommends that you should try the “double paddle pull” neutral rev and that “you will love it!”
The new LT2 engine was not without its challenges. The mid-engine Corvette has a lower engine position, enabling a lower center of gravity for the vehicle while also allowing it to be directly mounted to the engine to the DCT. This results in the engine being now 25mm closer to the ground than ever before.
Jordan refers to the new engine as a “jewel”, now that it is visible
through the rear hatch glass. To add to the aesthetics, the engine also features molded-in crossed flags, the addition of “Venthan Red” rocker covers, textured exhaust heat shields, and a stylized engine cover. Careful attention was paid to all visible components.
Other significant updates include an aluminum hub balancer, a new starter to manage a revised flywheel ratio, a new direct-injection fuel pump, and more.
Jordan also shared with the group that at Mark Reuss’ request, Tonawanda would be recognized with a “pride badge” on the LT2 which pays homage to the design of historic badge references used in the 1960s by Tonawanda.
The full seminar is available on the members-only section of the website to event registrants and Museum members.
