* Engine Mounts: The 350 Chevy uses different engine mounts than the original Cutlass engine. You'll need custom motor mounts or an aftermarket kit designed for this swap.
* Transmission: The transmission compatibility depends on what transmission came with the Cutlass and what transmission you're using with the 350. You might need an adapter plate, a different transmission entirely, or a custom driveshaft.
* Exhaust System: The exhaust system will need to be custom-fabricated to fit the 350.
* Wiring Harness: The wiring harness from the Cutlass likely won't work with the 350. You'll either need to modify the existing harness extensively, or use a custom harness designed for the swap.
* Cooling System: The cooling system may need modifications to accommodate the larger engine.
* Computer/ECU: The 350's engine management system (if it's not a carburetor setup) might not be compatible with the Cutlass's existing systems. This could require a standalone engine management system.
* Steering and other components: Depending on the size and placement of the 350, you may need to adjust or replace other components such as the steering column or power steering components.
In short, while it's *possible*, it's a major project requiring mechanical skills, fabrication skills, and potentially significant parts costs. It's not a beginner-level swap. You'll likely need to consult with experienced mechanics or enthusiasts who have done similar swaps before you start. Researching specific 350 swaps into G-body cars (the Cutlass is a G-body) will be beneficial.
