[DeTomaso] R.S. Thermo & restrictor plate ??

On my original, unmolested 351C block the brass bypass plate's top surface
measures 1.04 inches from the block's T-stat seat.

Bud,
 
The bypass plate has a 0.75 inch diameter hole with an area of 0.442 sq in.
 
The foot of the thermostat has a 0.66 inch diameter with an area of 0.342 sq
in.
 
The foot of the thermostat can block only 77.4% (0.342 x 100/0.442) of the
bypass plate hole if it is perfectly (unlikely) positioned vertically in the
bypass plate hole.
 
This means that 22.6% of the water volume which bypasses when the thermostat
is closed can still bypass when the thermostat is open.
 
Have fun today,
