1. Engine and Transmission:
* Engine Choice: Decide on a specific 350. Consider year, modifications (if any), and condition. A rebuilt or crate engine simplifies the process significantly.
* Transmission: The 292 likely had a manual transmission (likely a 4-speed, possibly a 3-speed). The 350 can use a variety of transmissions, including manual (SM465, NP435 are common choices) or automatic (TH350, TH400, 700R4 are possibilities). The transmission choice significantly impacts the swap's complexity. You'll need a bellhousing compatible with both the engine and transmission.
* Adapter Plate (Likely Required): The 292's bellhousing won't mate with a typical 350 Chevy. You'll almost certainly need an adapter plate to connect the new engine to your existing transmission, or you might need to replace the transmission entirely.
2. Engine Bay Modifications:
* Engine Mounts: The 350's dimensions are larger than the 292's. You'll need to fabricate or purchase new motor mounts to securely position the 350 in the engine bay. This might involve welding or significant modification to the existing frame.
* Clearances: The C60's engine bay may require modifications to accommodate the larger engine, potentially involving cutting and reshaping parts of the firewall, body, or frame.
* Exhaust System: You'll need a completely new exhaust system designed for the 350. This is a significant fabrication project involving headers, pipes, and mufflers.
3. Drivetrain and Axles:
* Driveshaft: The driveshaft length will need to be altered or replaced to accommodate the new engine and transmission. This often requires professional shortening or lengthening.
* Axles: The C60's axles might not be sufficiently robust for the significantly increased power of the 350. Consider upgrading axles depending on your intended use.
4. Cooling System:
* Radiator: You will likely need a larger radiator to adequately cool the more powerful 350.
* Cooling Fan: A more robust cooling fan might be necessary.
5. Fuel System:
* Fuel Pump: The 292's fuel pump won't be suitable for the 350.
* Fuel Lines: Fuel lines will likely need modification or replacement.
6. Electrical System:
* Wiring Harness: You may need to adapt or replace the wiring harness to accommodate the 350's electrical needs. This is a complex task requiring good electrical knowledge.
* Alternator: The alternator will be different.
7. Other Considerations:
* Professional Help: This is a very complex job. Unless you have significant experience in automotive mechanics and fabrication, it's strongly recommended to seek help from a professional mechanic or experienced hot rodder.
* Parts Sourcing: Finding the right adapter plates, motor mounts, and other specialized parts may require considerable research and effort.
* Safety: Working on a vehicle involves risks. Ensure you have the proper tools, knowledge, and safety precautions in place.
In short: This is a major project that goes far beyond a simple engine swap. It requires significant mechanical skills, specialized tools, and potentially professional assistance. A thorough research into specific parts and procedures is critical before beginning. Consider the cost and complexity before embarking on this task. Improperly performed, this conversion can be unsafe and unreliable.
