The Gen V LT engine is a monster motor and lets you install modern day power and reliabilty into your classic vehicle. These engine swap adapter plates adapt the mounting points on the LT engine to emulate the engine block mounting holes on a traditional SB Chevy block and they prepare your Gen V LT engine for installation into factory SB Chevy Cars and Trucks. To provide flexibility in design Trans-Dapt offers three different adapter plates that position the engine in one of three locations. This pair of adapter plates position the LT engine 1-1/8" rearward for additional accessory drive and radiator clearance. Mounting pads not included. For complete kits with pads and hardware refer to Trans-Dapt part #4526 (rubber) or 4527 (polyurethane).
