I live in the tropical hot northern part of Australia so we get pretty good at solving cooling issues.
On my 440 1969 barracuda I run two 16" electrics.
One pushing.
One pulling.
They are mounted on opposite sides of the rad to get maximum coverage.
The puller is thermostatically controlled and copes by itself much of the time.
The pusher is manually operated by an on/off switch in the cab and is used when really hot,prolonged idling,etc and it copes fine.
Might be an easier,cheaper idea for you to try?

i don't care how hot it is out. when cruising down the road you shouldn't need the fan. you should have enough air flow through the core to keep it cool. if not you have other issues. sure it isn't lean with the the hood sealed tot eh carb like that?. you need it at lower speeds and while sitting.
