Stage one done, made some flaps to get some more air flow through the radiator. Using some scrap stuff from around the garage. Roadkill style! Ordered a hood to radiator seal from Detroit Muscle.
Looks like a good start! You should seriously consider the air dam. It changes the pressure dynamics creating a low pressure region behind the radiator which results in increased air flow volume and velocity across it extracting more heat.
It would be the equivalent of adding two more electric fans to the front of the radiator.
