These Speed Engineering motor mount plates are designed for swapping a Gen V LT-series engine (LT1, LT4 or LT5) into an older car or truck. Made from 3/8" billet aluminum, they adapt the LT engine to small block Chevy motor mounts, so they work in almost any vehicle that originally came with a small block Chevy engine. The plates offer four engine positions: the stock SBC location, plus 0.625", 1.625" and 2.250" settings.
⚠️ Important Notes:
- The plates pair with small block Chevy style motor mounts (Gen 1, single-bolt Gen 2, or clam-shell styles depending on the vehicle)
