Yun's 1992 CORVETTE ZR1 LT5 368 (FULL REPAIR AND BUILD)
I initially asked Evolution Motorsport Engineering to re-build my beloved 368 LT5 after having a major issue with detonation, a head gasket failure and a possible catastrophic loss of oil pressure. This was the second build of this engine in a year and we HAD to get it right this time. Dempsey proceeded to document and tear down the entire engine to the cradle, we found multiple issues throughout the build (which he thoroughly documented and notified me of). Once the engine was completed. Everything I hoped we would gain from this build I got and more. I could not be happier with the results.
