what is a good radiator to use?

I am a fan of the Griffin direct fit with shoud mounts. Paint it radiator black, bolt up the shoud, and it looks like a factory piece. For the big block/A body application, I like the 26" wide Cuda radiator because the inlet /outlets are on the correct side for the aftermarket and most factory water pump housings

Never....never an over- heating issue. I have installed over a half dozen.

I buy from Summit/Atech and have had a couple show up with hidden damage, but Summit replaced no muss/ no fuss
