* The VIN: The Vehicle Identification Number (VIN) contains a code that indicates the engine. The VIN is usually located on the dashboard, visible through the windshield. You'll need to look up a Corvette VIN decoder specific to 1976 to interpret the engine code. Many online resources exist for this.
* The Engine Block itself: The engine block will have casting numbers stamped on it. These numbers can be used to identify the engine displacement (e.g., 350 cubic inches, 454 cubic inches). You'll need a reference guide or online database of Chevrolet engine casting numbers to decipher this information. The numbers are usually found on the block's side, near the front.
* Original Documents: If you have the original owner's manual, the build sheet, or other paperwork that came with the car, that would clearly specify the engine size.
* Prior Service Records: If you have service records from previous owners or mechanics, those records might list the engine size.
* Data Plate (Trim Tag): Located on the driver's side doorjamb, the trim tag lists many details about the car's specifications, but it *might not* explicitly state the engine size. It might provide codes that, when cross-referenced, can help determine the engine.
The VIN decoder is the most reliable and convenient method. If you have access to the VIN, that's the best place to start. Keep in mind that a previous owner might have swapped out the engine, so the information you find might not reflect the original engine.
