thick nylon spacer. I have already made an extra “skin” for the
muffler with insulation in between. I have also put on “header-tape”
on the exhaust j-pipe, so hopefully will all these extras give a cooler climate
for the carb.</span></font>

Bo, I have noticed the hot coil thing too, mine gets almost too hot to touch,
have not done it yet but plan to turn it over where the connectors are on the
top rather than bottom as someone had mentioned to me that coils should be
upright because of the oil in them???

Any comments?

On the hot carb, what I did was make a 1/2 phenolic spacer rather than the 1/4
spacer l fabricated a stainless steel heat shield that has heat wrap that
you would use on headers between two layers of SS sheetmetal to keep heat away
from carb, seems to work well as I don't have the vapor lock problem anymore. Fotos
if anyone wants to see.

About temperatures---I have a set engine
gauges in mine and the temps vary depending on outside air temp, how hard and
how long you run it---worse case is a hot day, 95 degrees and running on
freeway trying to keep up, going 70, after an hour of this the most I've seen
was 180 water temp and 220 on oil temp. My car likes 55 to 60 and will run all
day at 160 water temp and 190 to 200 oil temp. On a cool day water temp stays
about 140 and oil temp around 180, start up oil pressure is 50 and stays at 40
after warming up. While in the water these values are much lower as you are not
using half the rpms as on the road.

My car has no oil cooler and no thermostat in cooling system.

I'm pretty happy with things as they are
but next mod will be the larger pulley water pump to get rid of some of that
noise and if I ever find the right fan will reverse the direction of air
through the radiator, anyone know where I can get a fan made, I've found some
with the right pitch, you can't just turn it around but the bolt holes don't
match.

Anyway now maybe I can go back to
sleep-----</span></font><font face="Arial"><span style="font-family:Arial">
