If you are doing a swap, these billet aluminum LS1 Swap plates are just what you need.  These plates allow the installation of LS based engines into most vehicles that originally came with a SBC/BBC engine.  They are equipped with 4 adjustable positions, which allows adjustability with the LS based engine for proper placement.  These are designed to work with factory SBC/BBC motor mounts or factory clamshells.  Each plate is labeled “P” for passenger side and “D” for driver side. There is absolutely no grinding necessary for a flush fit.  Laser cut, water jetted or plasma cut parts do not compare to the quality, precision and accuracy of these CNC aluminum billet plates.  Hardware and instructions are included for proper installation.
