    Yeah that new Ford 7.3 gasser is impressive, seems to be very stout and torque happy. It's already in the 8's with a stock motor.

    I would add the fan. 206 is high IMO for just casual driving. Adding the fan would be the easiest thing to do.

    My 40k TruCool doesn't get above 150 F on the hottest of days here in FL.
