You'll need to purchase aftermarket engine mounts designed for a Chevy small-block swap into a G-body (the chassis type of the '86 Cutlass). Several manufacturers offer these, such as:
* UMI Performance: Known for high-quality performance parts.
* Energy Suspension: Offers polyurethane mounts for a more durable and potentially stiffer setup.
* Prothane: Similar to Energy Suspension, offering polyurethane options.
You might find mounts sold as a kit including crossmembers, or you might need to source them individually, depending on what kind of modifications you’ve already made.
Important Note: Finding the *correct* mounts depends heavily on:
* Specific year and model of the Cutlass: Even within the G-body platform, there might be subtle differences.
* Transmission used: Automatic or manual? The transmission location will affect mount placement.
* Engine accessories: The location of your alternator, power steering pump, etc., might influence mount choice.
Before purchasing any mounts, carefully research the specific manufacturer's instructions to ensure compatibility with your exact setup. It's advisable to consult with a mechanic experienced in engine swaps if you're not comfortable with this level of automotive modification.
