Are you talking about the 'nascar' series rad? if so, your stock fan will work, however you will have to trim your shroud in a few places for clearance (top rad hose) Also, your stock overflow cannot fit on the shroud because the lower hose output on the rad is in the way. I cut the bottom off my overflow, then resealed a new bottom on. Fits great now. I have since upgraded to the black magic electric fan which fits good and comes with a seperate bracket to secure your overflow - with it you could probably get away without cutting your overflow since the bracket will alow you to reposition it. Since the electric fan comes with it's own shroud - you wouldn't have to worry about trimming the stock shroud.
