Okay so basically,

1.) Biggest Radiator you can make fit
2.) Aluminum Radiator preferable
3.) Electric Fan with shroud that covers the most area of the radiator
4.) Good Water Pump

Got it!

I have been looking at the Summit radiators and it seem they are all 2 pass. I know other brands seem to indicate 2,3 and 4 core. Is this not necessary? Also, is it best to run a separate trans cooler rather then one in the radiator?

Thanks!
