- 350 bored over 30: This means that a small block Chevrolet engine with a 350 cubic inch displacement has been bored out to 30 thousandths of an inch over the standard bore size. Boring out the engine increases the cylinder diameter, allowing more air and fuel to enter the combustion chamber and increasing displacement.
- Flat top pistons: Flat top pistons are a type of piston that has a flat top surface, as opposed to a domed or dished top. Flat top pistons are often used in performance engines because they offer a more consistent combustion chamber shape and can help increase compression ratio.
- Hi torque closed chamber heads: Closed chamber heads are a type of cylinder head that has a combustion chamber that is enclosed by the cylinder head itself, rather than being formed by a separate cylinder head gasket. Closed chamber heads are often used in performance engines because they offer better sealing and can help increase compression ratio.
- 480 comp cam: A Comp Cam with a 480 lift is generally considered to have an aggressive profile. This means that it has a longer duration and higher lift than a stock camshaft, which allows more air to enter and exit the cylinders, increasing engine power.
- Edelbrock intake: The Edelbrock intake is an intake manifold designed to increase the flow of air and fuel into the engine. It is made by Edelbrock, a well-known manufacturer of automotive performance parts.
- Edelbrock 660 quad carb: The Edelbrock 660 quad carb is a 4-barrel carburetor (quad refers to the four barrels or throttle plates) that is designed to provide a good balance between performance and fuel economy. The 660 cfm (cubic feet per minute) rating indicates the air flow capacity of the carburetor.
Overall, this description seems to be referring to a modified small block Chevrolet engine that is designed for performance and torque, likely for use in a modified or high-performance vehicle.
