Good rundown, best I've seen. :thumbsup: I went with the FFD 2-core ($200 shipped) after trying a couple of the other less expensive rads on your list. None helped much, but the FFD cured all cooling issues with the stroker, especially the stuck in traffic on 199* days. It's about 1/4" thicker than most, but that required no modifications. If a radiator can be beautiful, this one was. The welds are works of art, and it's a solid heavy unit. I did however have to mod the lower auto tranny coolant aluminum elbow by using a tubing bender to tighten up the bend radius a bit for better clearance from the frame - no biggy. Customer support was great - I wanted a petcock instead of the supplied plug and asked. A quality brass petcock arrived a couple of days later in the mail free. Three plus years later - all is well.
