I'm shopping around for everything I want to replace when I install my new engine. I was already advised to get the Allstar Perf.radiator 3X pass with 2 1inch rows. It has an internal trans cooler. My question right now in shopping for a trans. Some come as kits with an external trans cooler. Would both be advised or overkill? The engines said to be around 500HP and going with a street/strip TH350. NOT to be raced just a street cruiser.
