Installing this gasket is a straightforward process. Simply remove the old gasket, clean the engine surface, and apply a thin layer of sealant if necessary. Then, carefully place the new gasket onto the engine and secure it in place.

Buying a GM 394790 NOS (New Old Stock) carburetor mounting gasket for a 1966-1967 Oldsmobile Cutlass can be a worthwhile investment for those restoring or working on their classic vehicles. Here are some potential advantages and disadvantages to consider before making a purchase:

Advantages:

1. OEM (Original Equipment Manufacturer) Part: This gasket is an original factory replacement part, ensuring a perfect fit and reliable sealing.

2. New and Unused: As a NOS item, the gasket is brand new and unused, unlike aftermarket or used gaskets that may have imperfections or wear.

3. Restoration Projects: For those restoring their Oldsmobile Cutlass, using an OEM NOS part helps maintain the authenticity and value of the vehicle.

4. Performance and Durability: A properly sealing carburetor mounting gasket can help improve engine performance and prevent leaks or other issues.

Disadvantages:

1. Cost: NOS parts can be more expensive than aftermarket or used parts due to their scarcity and original condition.

2. Availability: NOS parts may be harder to find than aftermarket or used parts, requiring more time and effort to locate.

3. Shipping and Handling: Since NOS parts are typically sourced from distributors rather than local auto parts stores, shipping and handling costs may be higher.

Conclusion:

The decision to buy a GM 394790 NOS carburetor mounting gasket for a 1966-1967 Oldsmobile Cutlass depends on individual priorities and circumstances. For those who value authenticity and reliability, the advantages of an OEM NOS part may outweigh the cost and availability concerns. Alternatively, for those on a budget or working on a tight timeline, an aftermarket or used gasket may be a more practical option. Ultimately, the choice is a personal one that balances the importance of originality, performance, and cost.

Recommendation:

If you're restoring a 1966-1967 Oldsmobile Cutlass and prioritize originality and reliability, a GM 394790 NOS carburetor mounting gasket is an excellent choice. However, if you're working on a budget or need a quick replacement, consider an aftermarket or used gasket as a more cost-effective alternative. Regardless of which option you choose, ensure that you purchase the correct part number to ensure a proper fit and function.
