Mpage7399, I am with you. I see pro mod race cars running with no radiators, but they shut down the motor after making each pass and they get towed back to the starting line. I am running an aluminum block and I do not have a vehicle to tow the car back to the pit area. I am installing a radiator and electric water pump. Working on mock-ups to figure out where to install the fuel cell in front of the radiator. If that does not work, will install the fuel cell in the trunk. I just do not feel comfortable running the car with no radiator. Will post a pic of the radiator this weekend. Love working on the old iron.
