Radiators

I bought a champion 22inch 3 core onebay for less than 200 shipped, no problem with installation.
what are you cooling with it? {engine size } are the tranny lines tight ? I really want that to be the solution but the bad press is a little off putting and I'm spending a goodly sum for the 410 I'm having built , sure don't want to kill it by buying a bad rad eh !
