How do you improve the performance on a car that is 35 years old? You can slowly swap out every component one by one or you can do what the brothers at Hardcore Engine Builders in Hungary did. They started with a tired C3 Corvette and stuffed the entire chassis and powertrain from a C6 Corvette under it. The team had to modify the chassis to fit under the classic body but the hard work definitely paid off. The Corvette now has all the modern features such as a 6.2 L LS3 V8, 6L80E six-speed automatic transmission, C6 suspension with Ridetech coilovers, ABS, traction control, and paddle shifters.

  1. Could you please provide the name of the shop(s) that made the C3 swap to C6 upgrades possible. I really would appreciate it. Having the ABS option included is a HUGE plus. Thank you.

  2. Imagine the Greenwood Leman s widebody C3 with that Chassis and a supercharged LS with a nasty cam and sidepipes, cruising down 66 anywhere, USA.

      1. The “Hardcore Engine Builders” link in your write up takes you to their Home Page. The bouncing red arrow in front of the phone numbers points to the cam shaft, and each lobe of the cam shaft is a different page. The “projects” page shows some of their other work.
