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.
