Description

Get reliable pulling power and classic hot rod clearance with the Edelbrock 46410 Performer Hi-Torq 350. This 5.7L build uses a tough 4-bolt main cast iron block and ships with a short water pump to clear tight custom radiator setups. Making a solid 363 HP with aluminum heads, a dual-plane intake, and a torque-focused cam, this small block runs smoothly on regular pump gas without breaking your budget.

Key Features of Edelbrock 46410 Performer Hi-Torq 350

• Short Water Pump Setup: Pulley hub sits closer to the engine block to easily clear radiators in 1930s to 1950s classic chassis.
• Cast Iron 4-Bolt Main Block: Keeps the lower end rigid to prevent bearing wear during heavy street cruising or hauling.
• Aluminum Cylinder Heads: Flows air smoothly and sheds heat faster than restrictive, heavy stock cast iron heads.
• Performer Hi-Torq Camshaft: Ground specifically to deliver a smooth, vacuum-friendly idle and massive low-RPM pulling power.
• Budget-Friendly Compression: Runs a safe 9.0:1 compression ratio so you can fill up with standard regular pump gas safely.
• Dual-Plane Intake Manifold: Arrives with an Edelbrock Performer aluminum intake pre-installed to boost bottom-end throttle response.
