I would think twice before going to the expense and trouble of changing to the thicker radiator.Apparently,frontal surface area is much more important than thickness for cooling capacity.Since our unshrouded fans leave significant surface area uncovered,this seems to be the key for better cooling for us.I agree that a thicker radiator would help ,but seems drastic and still does not guarantee to be the cure. A shroud or larger CFM fan seems most prudent. It is also pretty obvious that some motors run cooler given the same environment,so maybe timing could tame some overheating issues also.A high volume water pump with no underdrive pullys so the coolant passes through the radiator faster and with good volume would help.Some think slowing the flow through the radiator helps and this is not true. chuck
