Reply to "351 C Brass water restrictor under thermostat needed"

Another possibility exists: use a 2" brass freeze plug, available at about any parts store in the free world. You will no longer have the warm-up circuit in your water pump, but you will acquire the ability to run ANY Ford thermostat, since there will be no hole in the new freeze plug to accept the block-off cup on the bottom of a 351c-only thermostat. The change may cause your engine to run 10-15 degrees cooler as a bonus.
