On my '68 Barracuda, which was originally a Slant 6 car, I cut both sides out of the opening and had the bottom hose outlet moved over to fit a US Radiator I had been using effectively with a 440 in my E-Body to get it to work with the 5.9 Magnum I'm running. The fans are the max CFM Dual Spal 12" fans with their shroud and controller.
The black pieces in the picture are from the lower grill opening that I cut to better fit a pair of transmission plate coolers.
