I have a Summit direct fit aluminum radiator in my 69 bird. It bolted up nicely and the temps have not gone over 190- even when breaking-in the new engine in August. I had to cut a hole in the factory shroud for the upper hose because the actual core is not as wide as the original rad- the brackets, however, lined up well and the unit comes with a trans cooler.

I was told the summit radiators didn't have a lower drain. Is this right? That caused me to go with a 24" universal from jegs that i could see had a provision for a petcock on the bottom left side. $140.00 Today was my first test drive and it seems to have made a huge cooling difference. This is on a 67 with 400.

My Griffin does not have a drain either. PITA!!!!!

I have been toying with the idea of swapping out a new radiator. I am positive that there is crude in mine. 10 years of punishment and coolant swaps with 3 different engines. Temps are creeping up a hair.

With all of the aluminum rads so cheap, it is pointless to have it recored.. Just made up my mine. I am going to get a cross flow like the Griffin.

Huh... my '66 GTO Griffin has a drain. But it's a stock-style down-flow version.

And +1 more for the Griffin... the tanks are stamped and look pretty much factory, unlike most of the aftermarket alum rads that have tanks welded up from flat stock. I painted my top tank black and you have to look really closely to see that it's not a stocker.

Mine has a drain, but it's a direct fit radiator. Perhaps the universal types are the ones where one needs to check...
