run a 180 stat and drill 2 1/8 inch hole in the base plate of the thermostat.....

 

what is the hole for?

He means drill two seperate 1/8" holes in the outter frame of the
thermostat. This will allow some coolant flow even when the
thermostat is closed. It also keeps steam and air pockets purged
from the block, it's an old racers trick but it works. I usually drill
one hole in any thermostat I install, except for some Fords that
already have an air vent in them as a stock item.

Customer cars get one hole, personal cars get two holes and I
put three or four in my hot rods depending on how quickly they
get hot.

 

wow, i have to try that trick, now where do i drill these holes.
thanks

Drill two holes in the thermostat flange between the center hole
and the outter edge that contacts the manifold.
