[Oletrucks] Overheating 350 in my '58 Apache

[Robert Swanson]

Smokey,
	I have a high performance 396 that I installed in my 55 Cameo in 1970.  I am 
using an electric fan, no shroud, and synthetic oil (since 1978 ), and have 
never had an overheating problem in this configuration.  I have even hauled 
an 8ft Camper on the truck at 70 plus mph  ( when I had the heavy springs and 
3/4 ton rear end), and still not had a problem.  ( This was when I was living 
in southern Texas, which is slightly warm all summer )
	Other things you may need to check are timing ( retarding the timing a few 
degrees may help solve the problem), try running higher octane fuel, or add 
some octane boost to your fuel.  If you are running a higher compression 
engine, these new lower octane fuels can be a real problem.  I am running 
10.25:1 CR, and found I could eliminate the problems I had with low octane 
fuels.  I have a home designed system that I installed in 1975, but there 
used to be many water injection systems on the market.
