Check you the Champions... Toyota Land Cruiser Radiator (70-80)
They have many options. All are aluminum, you can add elec. fans, shrouds, overflow tanks, aluminum hoses, and polishing service. They have good reviews from what I have seen. 4+ stars on Amazon, Jegs, Google, and Summit. Just the 4 row radiator with no add-on is $270. That's a good deal I spec out a fully loaded one (fan, aluminum shroud, overflow, and hoses) for $584.
4-row may be overkill for a little 2F, but I don't like taking chances when I don't have to.
Had a brass four row back when the stock six was still running.
Could go over the grapevine in the hottest part of the summer pulling a travel trailer and the temp would barley touch the 200 mark.
It was fun passing all those newer vehicles along side of the road with their hoods up.
I am satisfied with the aluminum Champion 4 row I have now. It keeps the V8 cool in the summer.
