CNC-milled from billet aluminum and finished to OEM-style tolerances, the plates lift the crank centerline by 0.17 inches and include a center relief to clear the hump on many small-block mounts — eliminating the need to grind old mounts for a flush fit.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these adapter plates change engine fitment?\u003c\/h3\u003e\n\u003cp\u003eThe plates relocate the LS engine mounting points to align with your vehicle's existing small-block Chevy mounts. By raising the crank centerline by 0.17 inches and offering four adjustable positions, they help clear headers, oil pans, and steering components without major fabrication.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMoves crankshaft centerline up 0.17\" for correct driveline geometry\u003c\/li\u003e\n  \u003cli\u003eFour indexed positions to accommodate different oil pans and headers\u003c\/li\u003e\n  \u003cli\u003eCenter relief milled to avoid grinding factory mounts\u003c\/li\u003e\n  \u003cli\u003eDirect-bolt pattern compatibility with common SBC\/BBC mount locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat hardware and finish come with the adapter plates?\u003c\/h3\u003e\n\u003cp\u003eEach kit ships complete with the hardware needed for installation so you can bolt the plates to the motor and chassis without hunting down specialty fasteners.

These adapter plates are aimed at DIY engine-swappers, restorers, and fabricators converting classic SBC\/BBC vehicles to any common LS family engine. If you want CNC-accurate aluminum brackets, included hardware, and four-position adjustability to minimize clearancing and simplify installation, this kit is built to streamline an LS swap while preserving factory mount locations.
