well hissin i was thinkin bout a new radiator myself...i have had the car now for about 3 years and it has the same one that i bought it with..it is a griffen 3 core aluminum so i never changed it just figured it was good enough.......i looked at the car today and i noticed that the water pump pulley itself looks very large in diameter....so i took it upon myself to measure it and it was 6 inches...so i guess thats not too big or anything......so radiator down the line as well as a different water pump i am running one by the name of flow cooler from the summit mag tons of people say they never heard of it so i will be switching to an edelbrock just to ease my mind.....other then that just keepin my fingers crossed
