Product Description

The QA1 7740-374 LS Engine Mount Kit is a purpose-built solution for installing GM LS-series engines into 1963-1987 Chevy C10 trucks when paired with the QA1 crossmember. This kit simplifies engine installation by providing direct-fit mounting brackets that align with the crossmember and frame, reducing fabrication and ensuring secure, reliable engine placement.

Constructed from heavy-gauge steel and finished with a durable powder-coat, the brackets maintain engine location, support drivetrain alignment and withstand performance loads. With all required hardware included, the installation path is streamlined for both street and performance use. Whether you're building a restomod or high-output street machine, the 7740-374 gives you high-quality mounting architecture and peace of mind.

Before installation, confirm your vehicle is within the 1963-1987 C10 (or compatible GM chassis using QA1 crossmember) and that the crossmember is the QA1-specified unit. Double-check engine front-mount accessory clearance, drivetrain alignment, and frame integrity. Proper torqueing of mount hardware and post-installation inspection are advised to ensure safe and effective operation.
