Speedmaster PCE194.1004 Big Block Chevy 454 Electric Water Pump 35 GPM Chrome

The Speedmaster PCE194.1004 is a high-flow electric water pump engineered for Chevy Big Block 454 engines. By replacing the crank-driven mechanical pump, it eliminates parasitic horsepower loss and reduces rotating assembly drag — making it an ideal upgrade for performance street and race builds alike.

Key Features:

• 35+ GPM flow rate at 12 volts for maximum coolant circulation
• CNC-machined T-6 aluminum construction for lightweight strength and durability
• Direct-drive 12V motor with redesigned impeller on a stainless steel shaft
• Low 5.8-amp draw — minimizes electrical system load
• Superior RFI suppression for clean electrical operation
• Removable center section allows cam adjustment or replacement without full pump removal
• Inlet tube mounts left or right for flexible installation
• Hose adapter included — 1 in. NPT thread size, 1-3/4 in. inlet hose size
• Chrome finish for a polished, show-quality appearance
• Backed by a 12-Month Limited Worldwide Warranty

Because the PCE194.1004 operates independently of the crankshaft, it delivers consistent coolant flow at all engine speeds — including idle — where mechanical pumps typically underperform. The result is more reliable thermal management and more usable power at the wheels.
