Overheating issues with remanufactured 360
Let's see your cooling fan set up and radiator, what kind of fans are you using and does the shroud cover the radiator? Converter and cam are not the issue IMO, My 340 in my dart has a 3800 converter and 480/235 @50 solid cam with 28x19 summit universal radiator, I use a chevy HHR electric fan with shroud and have no cooling problems.
