These kits typically include:
* New motor mounts: These are designed to properly position the larger 455 in the engine bay. They will be different from the original mounts and may require modification to the frame or engine block.
* Adapter plates (possibly): Some kits might require adapter plates to bridge the gap between the 455's mounting points and the chassis.
* Hardware: Bolts, nuts, washers, etc., to securely install the mounts and engine.
Finding the right kit: You'll need to research suppliers specializing in classic Pontiac parts. Searching for "1966 GTO 455 motor mount kit" or "455 swap kit 1966 GTO" online will yield results from vendors like:
* Classic Industries: A large supplier of restoration parts.
* Ames Performance: Another major supplier of classic car parts.
* Year One: Specializes in muscle car restoration parts.
* Local speed shops: Check with your local performance shops as they may stock or be able to order the correct kit.
Important Note: Before purchasing, confirm the kit's compatibility with your specific '66 GTO and 455 engine. Engine year and model variations can affect mounting points. Contacting the supplier directly is always a good idea to ensure you're getting the right parts.
