* Engine mounts: The 350 Chevy engine will need to be fitted with the correct engine mounts in order to be properly installed in the Firebird.
* Transmission: The 350 Chevy engine will need to be mated to a compatible transmission. The original transmission from the Firebird may not be compatible with the 350 Chevy engine, so you may need to purchase a new transmission.
* Exhaust system: The exhaust system from the Firebird may not be compatible with the 350 Chevy engine, so you may need to purchase a new exhaust system.
* Fuel system: The fuel system from the Firebird may not be able to support the demands of the 350 Chevy engine, so you may need to upgrade the fuel system.
* Cooling system: The cooling system from the Firebird may not be able to keep the 350 Chevy engine cool, so you may need to upgrade the cooling system.
* Electrical system: The electrical system from the Firebird may not be able to support the demands of the 350 Chevy engine, so you may need to upgrade the electrical system.
Overall, it is possible to fit a 350 Chevy engine in a 1979 Firebird, but there are a number of things to consider before making the swap.
