Lingenfelter Performance Engineering debuted their twin-turbo 427 ci (7.0L) LT2 V8 capable of 1000+ hp (735 kW) to the wheels on 93 octane fuel and 15-16 psi (1.0-1.1 bar) of boost. The motor starts with a Lingenfelter sleeved LT2 block and features Callies 4.0-inch stroke eight-weight crankshaft, Callies H-beam rods, Mahle forged pistons, and Lingenfelter GT35 camshaft. Boost is generated by a twin-turbo system designed by Huron Speed using two Garrett G35-900 turbochargers, Turbosmart Hypergagte45 wastegates, and Huron Speed Bell air-to-water intercooler. Fuel is fed by a Lingenfelter big bore DI pump through Lingenfelter NOSTRUM Stage 2 DI injectors.
