[Tigers] Thermostat

[CoolVT at aol.com]

Jim,
The first thing that is recommended is to be sure that your  radiator is 
clear.  If it's plugged up all the other steps could be a  waste. If it's 
never been cleaned-rebuilt-recored that might be  a step to  consider.

Hi  All,

In some previous postings I have mentioned my Mk1 is tending to  run a bit 
hot
(220 or thereabouts) and recently has overflowed some coolant  through the
expansion tank hose. Seems OK on highway but in traffic or when  idling it
really heats up. I have check all hoses and retightened the fan  belt. As 
for
the fixes in the seminal Tiger Cooling article...I have a six  blade fan 
and I
have covered the horn holes. I have not installed the full  shroud-yet.
Radiator was recored by PO in 2001 but I do not know how many  rows.

As further background I have a 260 with the Edelbrock F4b intake,  Holley 
4160
4bbl (465 cfm), and the LAT 20 Hi-perfromance cam.

The  PO told me he used a 180 degree thermostat, but it must be at least  
5-8
years old I would think. I was thinking of replacing the thermostat as  the
next step in trying to improve cooling.

Question: What is the  consensus on the temp rating for a thermostat for the
260 with my set up?  Part number?

Any other thoughts are always welcome. I would be up the  creek w/o paddles 
if
it were not for the input I get from the  list.

OBTW: Stalling problem previously posted this  week seems to be corrected 
after
I adjusted carb float levels, idle  mixture, and curb idle. Also double 
checked
conenctor bolts and did vacuum  test which was OK.  Thanks.
