For years, I thought so, but the answer is a definite 'no'.

If you look at the other Ford engines, they all have a bypass hose which 
routes a certain amount of water past the radiator--some water just flows back 
into the water pump.

The 351C accomplishes this same thing by way of the 'hat' on the thermostat 
and the hole in the ring through which it passes.   John Christian did the 
math for me one day, comparing the total area of the opening in the bypass, 
with the total area of the hat which partially blocks it off.   Do the 
subtraction, and the remaining area is almost exactly the same as the area of the 
bypass hose on a 289/302/351W, and the FE motors.

Clever chaps, those Ford engineers. :>)
