Talk to the guy's that make the rad. They will know best what there rad can handel. a 22 from one manufacturer may work fine and then again a 26 from a different company may not handel it. I'd talk to the rad company or some speed shop owners who build race cars. They'd know what works keeping a big horse motor cool.

Here is a photo showing the relative placement of the 26" radiator to the radiator support.

Edit: I got it figured out. Here's the pic I pulled from PGClassics website. I am just going to do the conversion.

My stock 22" radiator for my 512 stroker would not keep it cool. Also tryed a 26" stock radiator also would not work. I called U.S. radiator and got one of there 22" 4 cores, does not go over 180 degrees. works great. cost around $600.00 though.but looks almost stock.

Did that a little while ago. They told me to go with the 26"

My Bee originally had a 22" radiator. 383 4 speed car... I will be going with a stroked 440 more than likely (prob. 600 hp). Will a 22" aluminum rad. get the job done? or do I need a 26"? I'd rather not cut the core support, but I need to know now because the engine bay is about to get paint.
