What kind of radiator?

I really do not see aluminum as an advantage in a street car for most applications. While anyone here can go argue (Without me) about the aluminum vs. standard rad.'s cooling abilty, I have found that the basics applied well and common sense when doing things will go along way.

For a easy, near zero hassle deal, a New OE rad. and electric fan will go a long way. Make sure the inside of the engine is dirt and rust free with new coolent.
IF you can use the stock shroud with the electic fan, use it. Craft one if you can. This helps cooling alot.
