Hi Tracy,I,ve been racing my 408(410)all summer long and have had no overheating problems.I run a stock 73 318 2 core rad(re-cored)with a 7 blade clutch fan,eddie alumi waterpump and add a small bottle of water-wetter(BeKool)with a 180 stat...no fan shroud.My car never goes over 180,even on the hottest summer days.This summer alone I have well over 125 passes and never once went over 180.Alot of racers kinda laugh at my simple setup,but hey..it works.I,m gonna say you have some blockage in your rad.I,d try some additive to your water or antifreeze??Maybe bad/cheap antifreeze??Good luck.:D

Yep.. I've seen setups like that many times that work good and guys with aftermarket stuff that looks trick doesn't work as good. I tried water wetter and it did help. I do have a 33% mix of antifreeze. Going from a 50/50 antifreeze/water mix to the 33% mix with water wetter dropped it a good 10 degrees.

BTW: how hot was your summer up there this year? It was well over 100 for nearly 4 weeks straight here. Hottest summer on record. I didn't even get the cuda out then it was so freakin hot. I'd hate to imagine how hot it would have ran in that temp.
