Default Radiator Upgrade?

I have a 01 TA auto with around 450rwhp. Noticed a tiny crack on radiator. Any upgraded radiators out there that are better than the stock one?

Before you upgrade, Do you have a stock cap on the radiator?

just a heads up on the LT1 radiators - they used to come with the 1.25" core that was a cooling upgrade but now all of them come with the 1" core. I ordered 3 different ones (including the Spectra) and all were 1". Also a few of them got damaged from shipping as you can see in the pic loI. I ended up going with the ECP radiator on my 02 Trans AM, auto. It's been on the car for about 2 months and works great so far.

When my OEM LS1 radiator leaked out of warranty, I bought a few cheap replacements, then bought a few Spectra LT1 replacements, they both eventually leaked at the plastic ends. I bought a DeWitts radiator before the pandemic and it's been solid... but boy have the prices increased

My car has the spectra on it and it’s a great radiator. When it starts leaking I will step up to the Dewitts. Hopefully it will give me several years, but we will see.

PWR might be an option.
