Dirty Dingo “Double-D” LS Engine Adapter Plates
Dirty Dingo Motorsports “Double-D” adapter plates are built for installing a 1997–2013 Gen III or Gen IV LS engine into older GM cars and trucks.
These adapter plates fit:
-
1958–1972 GM cars
-
1958–1972 2WD GM trucks
-
1962–1991 Corvettes
1958–1961 Corvettes require a frame stand when using a factory GM three-bolt motor mount.
Each plate is precision-machined from strong 1050 high-carbon steel. The bolt-in design makes it easier to replace a small-block or big-block Chevy engine with an LS-series engine.
Four Engine Mounting Positions
The Double-D adapter plates offer four engine positions:
-
Factory bellhousing position
-
11/16 inch forward
-
1 11/16 inches forward
-
2 1/4 inches forward
These are common engine positions used by major header manufacturers. The four mounting options help provide better clearance for the firewall, headers, transmission, and other parts.
Each kit includes a driver-side plate, passenger-side plate, and all required Grade 8 zinc-coated hardware.
