Aluminum Radiator for C3
I'm looking to reduce the temp of a 75 Corvette by 15+ degrees with new aluminum radiator. Was thinking of Dewitt but that's 500. Does anyone know a good reliable cheaper aluminum radiator for an every day driver? Thanks.

You are kicking a hornet's nest. 
Seems like everytime someone asks that, they get mobbed by Dewitt and his followers.
Look for a thread by Pauldana. He went with someone else's aluminum rad and was pretty happy with it.

I replaced the radiator in my 68 a couple years ago. Went to an aluminum one. I found a place on ebay that made radiators. I measured the size I needed gave them a call and got one for $175. Fit and works great! Lowered my engine temp too

Why? If you want to run cooler, Have a radiator shop rebuild your original with a high density core and then run a Stewart water pump and 160 degree thermostat. Mine never gets over 180 even on a hot day going up a hill.

Bought my Champion 4 row off eBay and the guy is first class to deal with. Told me if it didn't do what I needed he would refund my money including the shipping. Works great here in south Florida summers. I don't have A/C but 9.6:1 compression versus stock.

I have the '81 version in my car. I recommend it in every one of these threads and no one ever listens to me.

I just put my Champion 3 row in today as a matter of fact. It came with two 12" electric fans and I installed a thermostat switch as well. I don't know if i like the probe on the hayden thermostat switch but it works. I may buy a different unit that is a little more aesthetically pleasing. I have the fans comming on at 190.

Thanks everyone for the replies although my question was never answered.
Jim78SA, thanks for the info and in doing a search I know the 3 rows fit the small block 75' my question was about the 4 row.

For the OP. I had similar issue. In the end I replaced my radiator with a Dewitt's during their sale and it solved the issue. Reduced temps by over 20 degrees. Buy the zip corvette model for 399. It's made by Dewitt's. Some have had good luck with others but unsure if they are the same design and no way are they the same quality.

I had a 4 row champion it fit in Stock bracket but went with DeWitts after the champion should work good for stock engine I had a lot of trouble with the electric fan set up. Dewitts set up was one and done. But I think with original shroud if it doesnt break and fan clutch should be good. But for a couple hundred more you'll be set with a Dewitts
