Sure, no problem. All of our radiators feature dual 1" thick cores, for a total core thickness of 2". The original radiators used 1/2" cores, so an old style 4-core is the same thickness as our dual core. Most of our cores are 16 fins per inch, and a few are 15. We find that those are the optimum numbers of fins for cooling. Too few and you don't get as cool. Too many and you bottleneck the air and it can't pass through as quickly and gets hot. We use billet necks that we weld both inside and out. We put in drain ports on every radiator, and we include transmission coolers at no additional charge (can be used for power steering, oil, etc.). We also build them for engine conversion (ie: changing the port locations) for no additional charge. We are an American company, hand making a product using USA-sourced materials (something we take great pride in).
While I realize that there are many choices out there, we hope that you will give us a look. We aren't a large company strictly looking to make profit at any cost, instead we are a company that believes in American-Made products, and we also are hard-core automotive people that like to support our hobby.
