[franky 455]

I have a 1966 GTO with a Champion radiator ( not the fanciest, I know ) and at speed say 70mph on a 110 degree day, I'm in Australia, the temperature will get to 200 degree measured at the intake, too hot for me. Right now I only have the body of a Thermostat installed, I have a large Aluminium Clutch fan out of 1974 Firebird and two electric puller fans and two electric pusher fans ( see pictures attached ). I have a cast impeller and I have done the clearance thing. The engine is a 400 stroked to 461 with 30 thou. bored out, Butler Kit with stock heads. Is the water travelling too fast through the radiator? will a complete working thermostat be enough to slow it down? or should I use a reducer? What do you guys think?
Cheers.
