This is a retransmission of email (below) that I sent last night. I did not
receive it through the list so I figured nobody else did either.
Since I sent last nights email I reread the article on cooling and see 180
degree thermostat is recommended. So that answers my question.
But I have another...Has anybody blocked off the space between the crossmember
and radiator as mentioned in the article on cooling. The article says you can
use foam. Just wondering what type foam would be best...styrofoam, soft foam.
Seems awful hot in there for foam. Has anybody done this? Thoughts?
Thx,
Jim Lindner

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.
