TD Motion has put together a complete Thermostat Housing Assembly Kit part of it derives from the lower Cobra Earl Lower Housing. As some of you may know Earl no longer sells to the public due to health issues but we still have available.
The small block Fords have a lot of issues with getting Air Trapped and not allowing the Air to "Burp" from the Cooling system. Leading to hot spots and fooling the cooling system into thinking its full. This Housing assy will release all the air out of the cooling system. Runs more $$ than a cheap chrome plated steel housing that often leak and peel. This Assembly looks pretty cool under the Hood to Boot!!
