The new 2023 Corvette Z06 is on display at the Peterson Automotive Museum this morning. CorvetteBlogger contributor Jeremy Welborn managed to get into the museum before the crowds and was able to secure this interview with Chevrolet small-block assistant chief engineer Dustin Gardner.

Jeremy also gives us a great look at the cutaway LT6 flat-plane crank V8 engine that makes 670 horsepower at 8,400 and 460 lb-ft of torque at 6,300 rpm.

  1. The LT2 makes more torque. Couldn’t GM squeeze a little more torque out of that engine? It reminds of the GT500 and it’s 5.2 liter V8 where it makes less torque (625) vs (631) in the 5.8 liter V8. Both make substantially more horsepower but less torque. Yes this is more about horsepower, but torque should also increase not decrease.

  2. Torque is a function of cubic inches. A bigger engine makes more torque, a smaller one makes less. Simple as that…unless you add a turbo or supercharger…which will happen when they make the ZR-1 and Zora. Those numbers will truly blow everyone’s mind. And wallet.

  3. Great article. Thought the torque rating according to GM is significantly understated. Also, isn’t your RPM number inaccurate according to Chevrolet?

  4. I want to build one of these LT6 engines at the Performance Build Center, like I did my LT4. This engine is an engineering marvel, Thanks Jeremy for capturing this for us. As for the torque comments, the 4.2L Cadillac Blackwing engine in mt CT6-V makes 640 lb ft of torque, this LT6 engine being normally aspirated, still has plenty of torque at 460 lb ft. Add turbo charging for most likely some very hefty gains in a future application….lol
