Billet Aluminum Dirty Dingo Motorsports “Double-D” LS engine adapter plates are CNC machined from 1/2″ thick 6061-T6 aircraft billet aluminum on a precision vertical CNC milling center. These mounts are completely machined on both sides to 3/8″ thick and are designed as a true “bolt in” adapter plate for installing the 1997-2013 Gen III/IV LS series engine into 1958-72 GM cars and 2WD GM Trucks, and 1962 to 1991 Corvettes(Corvette 1958 to 1961 will require a frame stand to use a GM three bolt mount). These conversion plates will place your LS engine in the correct position when swapping from a small or big block Chevrolet engine to a LS series engine and have four different motor mount placement positions.

These are the most common engine positions for the major header manufacturers. No other conversion plates on the market are designed like these.
