How to Confirm Engine Matches Car Pontiac Trans Am

Introduction

The Pontiac Trans Am is a classic muscle car that was produced from 1969 to 2002. Over the years, the Trans Am has been powered by a variety of different engines, including the Pontiac 400, the Chevrolet 350, and the LS1. If you’re considering buying a Trans Am, it’s important to confirm that the engine matches the car. This will ensure that the car is original and that it has the correct performance characteristics.

Step 1: Check the VIN

The first step to confirming that the engine matches the car is to check the VIN. The VIN is a 17-digit code that is unique to each car. The VIN can be found on the driver’s side door jamb, the firewall, and the title. The eighth digit of the VIN indicates the engine code. For example, a Trans Am with a VIN that ends in “W” has a Pontiac 400 engine.

Step 2: Check the Engine Stamp

The engine stamp is another way to confirm the engine code. The engine stamp is located on the front of the engine block, near the distributor. The stamp will include the engine code, as well as the year and month of manufacture.

Step 3: Check the Engine Casting Number

The engine casting number is a unique number that is cast into the engine block. The casting number can be found on the side of the engine block, near the oil filter. The casting number will match the engine code.

Step 4: Check the Engine Assembly Stamp

The engine assembly stamp is a sticker that is placed on the engine during assembly. The assembly stamp will include the engine code, as well as the date of assembly. The assembly stamp can be found on the valve cover or the intake manifold.

Step 5: Check the Car’s History

If you’re still not sure if the engine matches the car, you can check the car’s history. The car’s history will include information about the original engine, as well as any engine replacements that have been made. The car’s history can be found in the car’s title, the registration, and the service records.

Conclusion

Confirming that the engine matches the car is an important step in buying a Pontiac Trans Am. By following the steps outlined in this article, you can ensure that you’re buying a car that is original and that has the correct performance characteristics.
