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. The first set of holes position the LS engine in the original bell housing position, then 11/16" forward, then 1 11/16" forward, and the last set position the LS engine 2 1/4 inches forward from the original bell housing position. These are the most common engine positions for the major header manufacturers. No other conversion plates on the market are designed like these. Includes left and right adapter plates and all necessary grade-8 zinc coated hardware.

ALUMINUM: Most of the aluminum alloys used today contain some level of lead, usually less than .1%. Lead is known to the state of California to cause cancer and reproductive harm. Most aluminum alloys are physiologically inert in their solid form, and the lead is contained within, however user-generated dust and/or fumes may pose a hazard if inhaled or ingested. Heating beyond a certain temperature may also provide avenues for exposure.
STEEL (steel bolts): Steel is an iron alloy with several metals including Nickel and Chromium. Both Nickel and Chromium are known to the State of California to cause cancer and reproductive harm, respectfully. This warning applies to stainless steels as well.
