Features
Vehicle Compatibility and Return Conditions.
This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.
Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.
Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.
Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase. For assistance or clarification, please contact customer support.

Engine 376 c.i. LS Builder Series Iron Block Standard Edition, Fuel Injected, TKX Manual Transmission
BluePrint Builder Series LS376/530HP Standard Edition EFI crate engine and TKX trans combos take the guesswork out of matching up an engine and transmission for your ride. Featuring a fuel injected Chevy LS small block-compatible 376 (c.i.d.) engine that produces 530 horsepower, this standard edition builder series includes a TKX manual transmission and pulley kit (pulley kit is an optional add-on, depending on the specific engine package you purchase). The aluminum BluePrint Engines cylinder heads help produce a nice 10.7:1 compression ratio, with assistance from the hydraulic roller camshaft, hypereutectic pistons, and nodular iron crankshaft. Altogether, this assembly produces 495 lbs.-ft. of torque. When you need or want a new LS powertrain for your ride, go with the authority in crate engines and their BluePrint Builder Series LS376/530HP Standard Edition EFI crate engine and TKX trans combos.
