Big Block Ford
Blue Anodized Finish

This plate is often used when converting to an electric pump. Many of our pump designs are not able to completely enclose the original water chamber in the cast aluminum timing covers such as are found in the big block Ford application. Use this back plate to seal up the timing cover and successfully complete your water pump installation.
Fits big block Ford 429 / 460 style engines
3/16' thick aluminum, CNC-machined

Built to Flow 35+ Gallons Per Minute!
Perfect for 12- and 16-Volt Electrical Systems

Mezieres aluminum 200 Series Electric Water Pumps are lightweight and flow 35+ gallons per minute. The pump housing, motor cap, and impeller are CNC-machined from 6061-T6 billet aluminum for superior corrosion resistance. A stainless steel impeller shaft runs through a carbon-ceramic seal that isolates the epoxy-coated motor from coolant for lasting reliability. The motor has a radio frequency suppression circuit to reduce ignition/RF interference. There are two motor options: standard duty and heavy duty (heavy duty offers more power and RPM with increased flow and pressure for street cars and other continuous applications where high-flow pumps aren't available). Most of these water pumps have 1'' NPT port(s) to direct flow using an inlet adapter of your choice (sold separately). Meziere offers extensions, longer inlets, and angle adapters if needed.

A great solution for problems stemming from radiators that are mounted low or horizontally, 200 Series Electric Water Pumps have a built-in expansion tank to act as a fill point and air separator. Returning the pressure cap to the low-pressure side allows easy filling of the system while the pump runs, and the level is maintained by purging air before any water escapes (i.e. air locking and cavitation are eliminated). Though specifically developed for dragsters where the radiator is placed flat in front of the driver or over the transmission, this design can help other vehicles with an inaccessible radiator.
