A whole bunch like my stuff , get the rad. up against the cradle where all air has to come thru the rad , even seal it w/ thin window insulation. .
I have front pusher fan , set to come on at 205 if I remember right . I just switched to thermal barrier coated headers to help w. the '' really hi'' engine bay heat.

yelow rose , andy f. , and stansblunblu have a lot of knowledge on this stuff !!
I experimented w/ this cooling problem all last summer , if ur pumping out big h/p , forget the all elec. fan thing , tho some have got good results w/ ford contour fans , thats about the only thing i didnt try. A belt driven mech. fan is about 7-8 degrees better than a clutch set up too , ''on mine ".
his fan doesnt look to have as much offset on the blades as mine ---??
