Cooling issue on highway

Bottom line I think I have an air flow issue.. going to make a simple airdamn off the bottom core support. Something like a 68 camaro.. Yes all these hemis run “hot”. I have 2020 technology in a 1968 chassis with very little aero.. maybe some air deflection is in order. I know some guys are die hard Mechanical fan ride or die but it’s not possible in this situation. With enough airflow in the right spot I think it will be possible. Need hot air to Go out also. I’m missing a seal on the hood. Also a big deal on new cars is pwm fans.. I can do that also which probably will happen. Going to start with some air dams

Pull the fan and shroud and test with them off first before spending money and time adding stuff to your car that you might not need and might not solve your problem anyway...
