I have this 11:1 347 in a '66 fairlane edelbrock wp rev rotation fox mustang belt drive champion 4 row radiator with dual fans and shroud. This thing get to 230 sitting still after awhile a little faster with the ac on. I've added a shop fan to the equation with little to no help. I am using a mr gasket t stat believe is 185 also by pass hose and heater core hooked up with no shut off valve on heater core. I am about to block off the heater and by pass completely and install a restrictor in the water outlet to force all water through this million dollar radiator that isn't currently helping me. My question is do these sbf need a bypass system with higher horse engine and living in houston tx. I understand that the wp needs to circulate all the time but living in Texas I think I understand that I need all the help I can get cooling this thing down. Oh yea I have the cyl head gaskets install with the "FRONT" in the front of the block on both sides and have performed a block test to check for blown head gaskets, none found. Please advise with your combo that works and your climate. Thank you.
