Billet Aluminum Dirty Dingo Motorsports "Double-D" LT engine adapter plates are CNC machined from 6061-T6 billet aluminum and are designed as a true "bolt in" adapter plate for installing the 2014-up Gen V LT series engine into 1958-72 GM cars and 2WD GM Trucks, and up to 1991 Corvettes. These conversion plates will place your LT engine in the correct position when swapping from a small or big block Chevrolet engine to a LT series engine and have four different motor mount placement positions. The first set of holes position the LT engine in the original bell housing position, then 11/16" forward, then 1 11/16" forward, and the last set position the LT 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.
