Brass Restrictor Plates NOW Available!

way to go Marlin!

would you like me to mention this on the Cleveland Forum?

...Yes George! Would You, Please! I tried to log on to one of those sites, but was unsuccessful. Thank-You! It was Your Words of encouragement that Motivated Me to see this through to a Finish...

OK Marlin,

there was a thread on the Cleveland Forum about the brass restrictors, so I posted an announcement about their availability.

Make a TON of money!

What are the advantages of using this restrictor plate?

the restrictor plate was installed by Ford in every 351C they manufactured. The cooling system cannot operate as designed without it. However, replacements have not been available for years. OEM restrictor plates sell on ebay for unreasonable amounts of money because they are so scarce.

If you are building a new 351C motor, or rebuilding your existing motor, the advantage is you now have a source for a oem quality new restrictor plate to install in your new or rebuilt motor. In the past you either had to search the wrecking yard for a usable used one, manufacture one yourself or redesign the cooling system.

Love your new member name!

Isn't it, that if you use an Edelbrock alloy waterpump the hole in the pump is closed, that you don't need the plate anymore?

No the Edelbrock aluminum water pump by-pass hole is open.

It is the Weiand pump that has the blocked recirc passage, not the Edelbrock pump.

Think for a moment. If the recirc passage is blocked, and the thermostat is closed (the motor is cold) how can the coolant pump circulate coolant? It can't, you have dead-headed the pump.

If there is no coolant circulating, what is happening to the coolant within the cylinder heads? It is turning into steam, forming steam pockets, the head is developing hot spots.

Then to make things worse, hot coolant finally migrates to the thermostat, the thermostat opens and allows a slug of cold coolant to circulate through the block, when the cold coolant hits the thermostat it slams closed again.

So you have a cylinder head with hot spots, then you thermally shock it with cold cooolant. And this happens over and over until the motor reaches operating temperature. and this happens every time you start the motor.

Sitting in the cockpit, you watch the needle on the temp gage stay at the far left of the dial instead of gradually moving up the scale. Then the needle pulses suddenly towards full scale stays there for a moment, and then swings back to the left end of the dial. It pulses over and over like this until the motor finally warms up.

There must be different pumps, mine from 1998 is closed at that section.

I installed mine last month. Here's a picture of the original Ford and the Edelbrock 8844.
