Cheapskate Cooling...

It would be nice to know what car/engine we are working with and what if any mods have been done.
73 Duster with a 410 Stroker with as many mods as I can afford! LOL but with that said as much cooling power as I can get LOL
I like the reviews on this? I can make anything fit it's just an old slant 6 car that I can cut or do anything I want. Of course I don't want to do too much if I don't have to, and also I was considering cutting the opening in the core support a couple inches on either side?
