Can't see the fan in the photo you posted, but suspect it is pulling air from everywhere EXCEPT through the radiator due to the lack of a shroud.

Don't make the rookie mistake of dropping down to a 160 thermostat in the mistaken belief that it will lower operating temps. HINT: When is the last time you saw a motor from the factory with a 160 thermostat?.....Like NEVER. Use a minimum 195 thermostat and bring the rest of the cooling system up to par with good engineering principles. Internal combustion engines need to run at least 195 to achieve the desired efficiency the motor needs for good power and good gas mileage and also to burn off acids in the oil that blow past the rings as a result of the combustion process.

Here is a pretty good tutorial on cooling that I wrote originally and that has been added to by several other hot rodders.....
