Before getting into whether it is necessary or not to drill holes in your
heads, how old are your fans?
If your car doesn't overheat at highway speed, then the cooling system is
capable of cooling the engine if it gets enough airflow through the
radiator.
If you had trapped air, I would expect it to overheat on the highway and in
traffic. Granted, if you have air trapped then your system may be
sufficiently compromised so as to have problems at the limit, but if your
car doesn't overheat on the highway, then your cooling system is capable of
coping.

Dear Friends,
My Cooling system is set up as follows;
fluidyne radiator leaning forward
sucker fans on ALL the time
Antifreeze 50/50 blend
New High Flow Water pump
160 thermostat( correct for cleveland)
I Used this tool to suck all air out of system and put the antifreeze back
in:
UView 550000 Airlift Cooling System Leak Checker and Airlock Purge Tool Kit
On the open road the car runs at a steady 180. As soon as I get into stop
and go traffic or go from waiting at red lights I can see the temp gauge
start climbing 220 plus . In the heat of the summer months I feel like the
car is ready to blow hoses.
I have read that guys here in the group have cars that sit in the desert
sun all day and the temp gauge barely moves. Either their gauges are broken
or I have a system that the antifreeze is just not flowing and cooling
.When I bought the car three years ago the guy said," If you are caught in
traffic ,just pull over". I refuse to believe that Detomaso designed the
car to
overheat. I see Ferrari's,Lambo's and Porsche run cool.So why can't the
Pantera?
I told my high temp issues to a guy last week at one of the cruise in's
and he said to me that back in the 70's and 80's he developed a system that
would lower the cooling temp by at least 20 degrees. He said that the
cleveland engine in a pantera leans down at the firewall and the heads will
always get air trapped at the rear of the head.(back of car) Causing there
airlock situation and therefore restricting flow.
What he does is drill a hole into each head and runs stainless lines to
the pressure tank or the the overflow tank,I forgot which one.
Does this make sense to anyone ? Has anyone every done this and had
success?
This guy did not seem like a typical back yard mechanic .He designed this
process while he was working for a speed shop out here in New York called
Motion.
Please let me know your thoughts .
Regards,
Bob Levitt
