radiator

Food for thought, most Aluminum aftermarket Radiators are thicker and narrow the distance between the water pump and radiator and the use of a stock shroud leaves gaps to fill. Most aftermarket electric fans do not pull enough air to cool. There are some OEM ones people retrofit that do. MK VIII, Taurus, HHR, Contour are a few donor cars people use and you need some form of proper control for them.

On the trans side are you running a high stall converter or running a lot on the strip? There are several ways to add auxiliary cooling to the trans but we need to know more about the car and chassis set up. i.e is this an open wheel dragster or a stock, full interior street cruiser?
