Radiator needs
Doesn't have to be reverse flow. Doesn't have to be anything special at all. Chances are the one already in your truck will work. LS motors don't seem particularly hard to cool.
It might be worth upgrading because modern aluminum radiators are a good bit more efficient and weigh less than the old brass ones. The one in my Datsun is out of an astro van. Works fine

Standard flow direction for the Radiator, most anything will work. Just have to worry about cooling capacity.
Note, most older GM Radiators have a larger top/inlet (return) on the Radiator. As the LS Water pump has a smaller size.. not a big issue, but something to mod on the radiator or use reducers for the hoses. Some Hose have different size on each end of the hose and you might find one that works.
Some of the newer aftermarket Radiator are duel sized port on the upper return inlet. My does and I got if from eBay.
