700 HP Cadillac Blackwing LT-Series Engine & 10L90 10-Speed Automatic Transmission Package

Cadillac Blackwing LT4 engine and 10L90 transmission package brings 700 HP of supercharged LT-series V8 performance to custom engine swaps, restomods, pro-touring builds, and high-performance projects. Combining a Blackwing-spec 6.2L supercharged V8 with a GM 10L90 10-speed automatic transmission, this complete powertrain package gives builders an integrated engine and transmission solution.

The LT4 engine features an aluminum small-block construction, high-pressure direct injection, forced induction, and forged internal components designed for high-output applications. The integrated supercharger, intercooler, and throttle body are included with the complete engine assembly.

For the transmission side, this LT4 10L90 package pairs the supercharged V8 with a heavy-duty 10L90 transmission. Its 10-speed automatic design provides a wide gear-ratio spread and electronically controlled shifting, allowing the engine to stay within its usable power range through acceleration while providing overdrive gearing for highway cruising.
