Details on the new V8 are sketchy but right now all we know is that the new engine is currently going through dyno trials, is based on the new next-generation Chevy small block and will be ready for Sebring, according to Corvette Racing program manager Doug Fehan. Doug’s words about the new engine seem encouraging, which you read for yourself below.

Fehan: "GM Powertrain has completed the initial dynamometer tests of the 5.5-liter small-block V8, and the race team has conducted the first track test with the new engine. We are quite satisfied with its performance level at this point. We plan to continue development and introduce the 5.5-liter engine package in competition at Sebring."
