Import Cadillac Lt4 Supercharged 6.2l Engine & 10-Speed Automatic Transmission Combo Complete Drop-In Package — Buy in wholesale FOB from Supplier in United States

The package offered by Buds Auto Parts combines a Cadillac 6.2 L LT4 supercharged V8 engine with a GM 10L90 10‑speed automatic transmission in a ready‑to‑run drop‑in unit. The LT4 engine features an aluminium block and heads, an Eaton TVS R1740 supercharger and delivers factory‑rated output of more than 640 horsepower and 630 lb‑ft of torque. All ancillary components such as coil packs, sensors, throttle body, pulleys, belts and the complete wiring harness are included.

The engine’s displacement of 6.2 L and its direct‑injection system are typical for high‑output Cadillac V‑series powerplants, while the aluminium construction keeps overall weight lower than iron blocks. Typical compression ratio for the LT4 family is around 9.5 : 1 and a red‑line near 6 500 rpm, which aligns with the supercharger’s boost characteristics. The 10L90 transmission is rated for up to 715 lb‑ft of torque and provides ten forward ratios that optimise acceleration and fuel‑efficiency across a wide speed range. Standard gear‑ratio spread and a lock‑up torque converter are part of the factory design, reducing drivetrain losses.

This turnkey powertrain is aimed at performance‑oriented rebuilds, race‑team swaps and high‑output replacement projects where a complete, pre‑assembled unit saves engineering time. Potential buyers such as tuners, specialty shops and import distributors should confirm that the engine mounts and transmission bell housing match their chassis before purchase. Because Buds Auto Parts does not publish MOQ, lead‑time or payment terms, interested parties must request those details directly from the supplier.
