i have an auto 76 280. the other day while i was driving, the car was running really hot, about 3/4 up the temp gauge, it usually hangs at around 1/3 [email protected] 70-80.anyway, i checked the coolant and it was one gallon low. so i took it to my local radiaitor shop.the guy told me that i have fin rot, which i believe, the thing looks like utter ****. anyway the question is he said that i should have him recore it because most aftermarket radiators are junk. he said $250-$270 for the recore and all labor with a five year guarantee. i looked and the motorsport 4 core radiatoris 250. has anyone put in a motorsport 4 core, and how well did it hold up. i would appreciate any info.
