I put one of those 2 core radiators from champion (they sell it on ebay) and my car slowly creaps up when I drive it. I decided to replae it and was wondering what everyone has had good experiences with? Im on a budget and dont really care about weight aswell!

Specs on my car are in my signature but doesnt matter what kind of car you put the rad in also Im not looking to here what people think are good rads on want to know if you have installed a rad that worked really well.

I was going to get a spectra 4 core from rockauto.com but I want to know if there is a better rad out there for the money .

I want something I can put in and drive no matter how hot it is, no matter if im in traffic, or constantly pounding on it, I DONT WANT TO WATCH THE TEMPATURE GAUGE! that is priceless to me !

I use a champion 3 core with my 455 and it cools fine cruising at 2800-3000 rpm. I did have a cooling issue a few months ago and I suspected maybe the radiator wasn't big enough but it ended up being a bad thermostat that was only a year old.

I went with a Summit 2 Core Aluminum. Best Radiator I have ever used for the money. It was $300 and my stroked 455 runs at about 170-175 degrees in the middle of the summer.

I did the water pump and found that the divider plate had alot of space, so maybe before I spend the money on a 4 core I should change the thermostat and test it out.

Stock 4 row is an option you can use with any CID. I have had the same stock (replacement) 4 row in the Formula for 26 years.

Bowties are for Pee-wee Herman. "Chevy": even the name sounds cheap, but not as cheap as your Pontiac will be with an LS transplant.

I don't think it's your radiator. I just - last night - replaced my stock 4 core that 3 different engines ran hot on. I used the American Eagle (made by Champion) 2 row aluminum and in test runs (hard runs) the car is running 25 to 50 degrees cooler than ever. You said you checked the clearence on the pump divider plate, try the thermostat. What are you running for timing? What type of fan and how big? How does your fan sit - should be apx half way in and half way out of the shroud? How is your shroud? How much clearence between the edge of the shroud and the fan blades and inch or less is nneded. Some people find they have an 18 inch fan where they should have a 19 1/2 inch fan. How is the seal between the shroud and the radiator? Large gaps are no good as air will take the path of least resistance.

Just some things to consider. I have fought the battle for a decade and finally I think the rad curred it. This is why I am surprised about your situation and don't think its the radiator.

Good luck!

Just a stock replacement 4 row radiator from a local radiator shop. Is your 2 row radiator a stock type or some sort of aluminum aftermarket type? If a stock replacement 2 row, that is basically a 6 cylinder type radiator back in the day. The 350-400 engines typically used 3 row at a minimum with 4 row used for hi-po 400 and all 455's. At least, that was my observation during the heyday.
