BluePrint Builder Series LS427/585HP Standard Edition EFI Crate Engine and TKX Transmission Combos

The BluePrint Builder Series LS427/585HP Standard Edition EFI crate engine and TKX transmission combo is a complete, performance-focused powertrain package for classic cars or hot rods. It features a powerful 427 cu. in., 585 hp, fuel-injected GM LS-style engine built with forged internals for reliability—paired with a strong TREMEC TKX manual transmission to handle the power. The kit is designed as a plug-and-play solution with accessories, ECU, and harness for easier installation. It offers big-cubic-inch V8 power (like a big block) in a compact small block LS format, ideal for swaps.

Key components:

* Engine (LS427/585 hp): A strong cast iron block, 427 cu. in. (7.0L) LS-compatible engine with aluminum heads, forged crank and pistons, hydraulic roller cam, producing around 585 hp and 520 lbs.-ft. of torque, with EFI for modern performance
* Transmission (TKX): A robust, modern manual transmission built to handle high torque, known for smooth shifting
* Accessories: Comes with front-drive accessories (alternator, pulleys) and a swap-ready oil pan
* Electronics: Includes a complete EFI system with ECU, wiring harness, and drive-by-wire pedal for engine management
* This combo is ideal for:
-- Enthusiasts building custom cars, hot rods, or restomods
-- Those wanting significant power (585 hp) and the engagement of a manual transmission
-- People looking for a complete, tested drivetrain assembly to simplify complex engine swaps
* Combo benefits:
-- Power and drivability: Delivers big-block-style power with the efficiency and responsiveness of modern EFI
-- Convenience: Comes pre-assembled and tested, reducing build time and guesswork
-- Quality: Uses high-strength components (forged internals, aluminum heads) for durability
