Summit radiator SUM-380459

I'm sure that would cool fine. I had one of their universal 26" radiators in my duster 408 SB and I actually had to put a higher thermostat in it because it cooled so well. The universal ones are real easy to mount, and they are around $170 if memory serves me right. But you do have to have an auxillery trans cooler. Oh yeah, I ran mine with a homemade shroud. Made it from galvanized sheeting and pop-rivits.
