GM's 369KW New Atmo V8

Delving deep on LT2, the new dry-sumped small-block powering Chevy’s C8 Corvette

COME 2020, CHEVROLET will build the most significantly changed Corvette in history and place the engine behind the driver. Unlike its superseded front-engine layout, though, the atmo V8 engine at its core will walk a path of evolution rather than revolution.

Dubbed the LT2 and powering the base Stingray variant, the new engine evolves from the LT1 small-block V8 that debuted in the C7 Stingray and currently powers the Camaro 2SS. So that means its 103.3mm bore and 92.0mm stroke remain, its 6162cc capacity carries over, the compression ratio is still 11.5:1 and its valves span the same 54mm diameter on the intake side and 40.4mm for the exhausts. Even the throttle body stays 87mm.
