I don't have much to add with regards to a. 5.3 in one but in the early 00's I put a stock sbc in a square early model 2wd s10 blazer.

I used the recommended corvette radiator and managed to cram a flex fan in between the two. By in large the truck didn't overheat if moving. Even towing a car in a trailer. BUT it had a major airflow issue pulling air through the rad and out the engine bay. If it was very warm out and I left the truck idling parked the temp would slowly steadily climb till it overheated. I discovered that opening the hood all but eliminated the problem. Hence the airflow problem.

Pick up a replacement from jegs, summit, eBay that will work that should be for a v8 or is rated for power. It isn't anything specific, the flat front of these trucks makes it easy for cooling. For fans, I use factory LS1 camaro/firebird dual fans.

Intrepid fans seem to be the thing in a v8s10 now. Cheap and easy to find and fit most radiators that go in the core support. This is a superior radiator with intrepid fans on my 93 core support. Little trimming and they fit nice. They cool real well too

LS motors aren't particularly hard to cool. I think a lot of that has to do with modern aluminum radiators. I don't know about that particular Jegs fan but I know OEM fans move a ton of air. Find a junk yard pull out that fits your radiator and you will be golden.

Pretty much, I always used the factory third gen camaro radiators and have no problems. With a 3 speed and 4.30s it will get to 200 or so in the summer.

Is that drove on the streets with 4.30s? Whats traction like? What about throttle response, iv been thinkin heavily about 4.30s wen I get my 8.8, I'm runnin a th350 3 speed as well

Fuel mileage was horrible, has a 4L80 now. Traction, well, with radials it was not great but it still would roll out if you feathered it. With the 4.30s and 6 speed it did ok with 28x14.5x16 et streets.
