I am putting a ls1 with over 450 horse in my 80 cj7 I wanted to know what radiator people are running. The best fit seems to be around 26X19 I want dual rows and a 1.25 or 1.50 tube. Just want to get the best cooling!!!
I ran a 1.5 aluminum rad on my LT1 and there notorius for overheating and had no overheating probs. Also ran a 160* thermostate, oyah make sure u set it up reverse flow, fukin jiffylube kids hooked up a coolant flush backwards on my and hydro locked my cylinders. Bastards how to pull every plug. Goodluck with yours though.
Ron Davis is the best around. Most expensive too. But you'll never have a problem. They can also do a double pass radiator if your really worried about it. I have one with the shroud and fan built in. Very nice unit.
I'm running a stock 4.0 radiator with my 6.0, along with a 160 degree thermostat and taurus fan. Generally lives around 180-185 degrees offroad. I've only run when it's 70-80 degrees though, we'll see what happens when summer gets here.
