Picked up a new aluminum radiator for my 55 with a LS3 truck motor yesterday. Stumbled across this company I hadn't heard of before that makes all of their radiators in house to order, and it was only a 2 hour drive away to pick it up. I timed it to pick up my grandkids in the same town just a mile away from the shop in a little farm town in Humbolt, Iowa. I was impressed with their operation and customer service. I called on Monday to order it, and it was done 2 days later. They buy blank cores, and then cut everything on a CNC waterjet and TIG weld them on site. They have a lot of different options and I decided to go with a top tank radiator with all of the correct size fittings to connect up to a LS engine. It also has a tranny cooler, Spal fan, shroud, and brackets all ready to bolt in. Looks like it will work great. I got it for little under $600 since it didn't need packaging, or shipped.
The company is Universal Parts Inc.
