I have had good luck with Engineered Cooling Products radiators. I don't know if they make them for the 67-68 years, but my two row keeps the 306 plenty cool even in stop in go traffic in 100F temps. I previously had one of the more expensive 4 row units, it worked well but not as good as the large two row radiator. Also make sure you use some sort of sacrificial anode to protect the radiator. I lost the first one in two years from galvanic corrosion.

Griffin Aluminum Radiator.7-568BC-FXX

I installed this on my 390. This was back in '05

Northern Radiators are good in my book. I've had the same one in the 66 since 2004. No problems.

I bought a US Radiator produced radiator (brass and cooper, I realize you're looking for aluminum recommendations but thought I'd throw this out as an option ) when I did all my upgrades in 2017/18 on the recommendation of Rick at NPD. On the expensive side but after putting so much of my wife's money into the rebuilding of the 289, I didn't want to cheap out on the cooling aspect of it. YMMV

If you search the old posts here you will find way back when as I was putting my car together I spent a lot of time in this area and found ECP (Engineered Cooling Products) and eventually went with a unit from them. They are local to the Chicago area which was a big deciding factor for me. In the end, I couldn't be happier. Their unit made for a 65/66 handles the job and has for many, many years now. Mine is a high compression, bored and stroked 347. I DRIVE IT HARD. I have no concerns about cooling. I've sat in rush hour traffic for hours without it ever seeing temp creep.

The key to a good aluminum radiator is how it is constructed. Has to be quality alloy. The welds need to be done correctly. If not you can see cracking, etc. Most important is the design of the cooling tubes, etc. ECP was one of the very first to understand that a bigger set of two rows out performs any three or four row with equal radiator (tube) depth. It's pretty basic math to calculate surface areas of all to see that two one inch tubes can dissipate more heat all other things equal. You've also got less welds ect. to worry about failing.

Did I mention that historically ECP is also on the lower pricing scale?!
