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
