ICT Billet SBC to LS Engine Mount Adapter Plate - Adjustable LS Swap

In this review the ICT Billet SBC Vehicle to LS Engine Mount Adapter Plate is evaluated for enthusiasts doing small block to LS conversions who need a precise, durable mounting solution. The single biggest reason to buy is its OEM-based fitment and billet construction that moves the crankshaft centerline up 0.17 in, which simplifies clearance and alignment during an LS swap. The plate set arrives as a clear, complete kit and is aimed at anyone wanting a clean, stable adapter without extensive modification.

Key Features

• OEM specifications: Built to OEM dimensions for better fitment, reducing the need for trial-and-error during installation.
• Crankshaft centerline raise: Moves the centerline up 0.17 in to improve driveline alignment in many SBC-to-LS conversions.
• Billet aluminum construction: Machined from 3/8 in aerospace-grade, USA-produced aluminum for strength and corrosion resistance.
• Complete hardware: Includes 2 adapter plates, 8 flat head bolts, and 6 flange M10-1.5 bolts so installers have the M10-threaded plates and necessary fasteners.
• Natural finish: The uncoated natural aluminum looks clean under the hood and resists surface wear.

Who It's For

This bracket set is aimed at DIY mechanics, engine builders, and swap shops performing an LS swap into vehicles originally equipped with a small block Chevy layout who want a billet, USA-made mounting solution. Its OEM-style machining and included fasteners make it convenient for those who prefer bolt-on results rather than extensive fabrication.

It is less suitable for users who must retain factory SBC mount brackets or for swaps with highly modified engine bays where custom mounts are required; a small number of customers reported mixed compatibility with factory SBC mounts, so check your setup before ordering.

Pros & Cons

Pros

• Well machined from aerospace-grade billet for a precise, durable mount that holds alignment under load.
• Includes required hardware and uses M10-threaded plates, reducing parts sourcing and simplifying installation.
• Raised crank centerline of 0.17 in addresses driveline and clearance issues common to LS swaps.
• Made in the USA with a natural finish that looks tidy under the hood.

Cons

• Compatibility is mixed with some factory SBC mount brackets, so confirmation of fit is necessary before purchase.
• The natural billet finish is uncoated, which some buyers may prefer to anodize or protect for long-term appearance.

Specifications

Our Verdict

The ICT Billet SBC to LS adapter plate is a solid choice for anyone performing a straightforward LS swap who values precision machining and an all-included hardware kit. It provides practical benefits like the 0.17 in centerline raise and durable billet construction, making it good value for builders who want a reliable, USA-made mount; double-check compatibility with any remaining factory SBC brackets before fitting.

Frequently Asked Questions

Does this kit include all mounting hardware?
Yes, it ships with 2 plates, 8 flat head bolts, and 6 flange M10-1.5 bolts; the plates are M10 threaded and the necessary hardware is provided.

How much does it move the crankshaft centerline?
The adapter plates move the crankshaft centerline up 0.17 in in the vehicle, which helps driveline alignment in many swaps.

Will it fit without modifying factory SBC mount brackets?
Many users report a clean bolt-on fit, but compatibility is mixed with some factory SBC mount brackets, so verify your specific mounts before installation.
