Drop in Aluminum Radiator Under $300?

[TURNA]

That guy has some strong opinions. I came across his site years ago when I was shopping for a radiator for my GP. I'm not smart enough to debate all his claims. I was real proud of my brother's expensive USA aluminum radiator until it failed. At least Champion stands behind their product. I would think a third row would increase capacity and cooling. According to their site, the Champion 2 row has 0.75" tubes. The 3 row has 0.63" tubes. Those ECP radiators look nice and he stands behind them. He lists one for a MC but only with electric fans. If you called, I suspect he would sell just the radiator.

The Champion we bought for my brother's car is a 3 row, but its a dual pass since the inlet and outlet are both on the passenger side.

I like that guy, I have his radiator fan setup in both the Malibu and Cutlass! both stay at 180

**and his wiring kit

This will funnel all the air though the radiator for max cooling.
And a good electric fan with a thermostat switch.

I have used several of their radiators, including their G-body model. It has 7887 in its part number. It cools my 508HP small block Chev.

Just looked at their Chevy listing & kinda wish I found this before I got my Cold Case. Looks like an OE & is cheaper, but don't see how long the warranty is for.

I was going suggest the Autocity rad, I am planning on one for my 70S with the 28.5" core, I may try the dual fans and shroud as well. Their Ebay rads says Lifetime warranty.

I think summit should be able to accommodate your needs. I have a summit brand aluminum rad in my cutlass. It's made by a company called Nathan. Its affordable and requires very minors modification to fit. I didn't have to do nothing crazy like welding, making brackets or cutting anything on the car. I was able to use the factory bushings and v-8 mounting bracket.

You're getting way to caught up on size. The last radiator you linked will keep a 350HP motor cool at idle without issue. Engines that don't cool usually have another issue.

We're using an triple pass Allstar Performance unit that doesn't fit with the stock top mounting bracket. The thing is rated for either 450 or 500HP. We make close to 800 and the damn thing overcools other than at idle, but we are using 1:1 pulley ratios than contribute to temps higher at idle than at full load.

If you're using stock pulley ratios and your tune is good, then one linked above will get it done for a small block.

Holley's Frostbite brand dropped right in for me, I have the FB163 (3 row), but here's link for 2 row model.

It's 26x18 so it's not "dinky". You got other issues then if you can't cool with that radiator. The typical GN replacement is the Camaro version of that same radiator and and that's with an intercooler in the way.
