You should read the cooling system section in the mechanics handbook?
One look at a BMW X5s cooling system and you'll get some new insight?
You are dealing with 50 year old technology with your 460s that virtually never overheat anyway
Dave you study that X5, et al. and report back
I'm not going to bother explaining that system to you unless you need me to
It absolutely requires time. I say Time again in the radiator
You can have tons of airflow and that lessens the time but it still requires an amount of time

Time in the radiator is not a factor and causing the system to cool more effectively by restricting the outlet only does one thing and that's causing the dynamic pressure generated by the pump inside of the block and heads to be higher. In order to maintain temperature you have X amount of heat to remove and that's all there is to the problem. That heat can be brought to the airstream by the coolant flowing slowly(greater difference in temperature from the radiator inlet to outlet) or by flowing faster (lower temperature difference between inlet and outlet) and it will make no difference in the amount of heat that's removed from the coolant. It's sort of like moving a given amount of water using two different size jugs. The larger one moves more water per trip but the trips take longer. The smaller cup moves less water per trip but it makes more trips.

the thermo is a new high flow shaw and the engine has just been rebuilt. its a aftermarket mechanical fan i dont remember brand. no clutch though. i would assume that the machine shops cleaning would have taken care of any blockage but maybe im wrong.

thanks! what i worry about with that is if the one i have now is inadequate a smaller one almost certainly would be. and im all about saving money but i would hate to ruin a high dollar motor trying to save a buck
