Yes and no. It offers quite a lot of cooling capacity and fairly low water resistance for not much money. The issue is that these cores are 2" thick and present
air resistance, so it's hard to find very quiet fans that can move enough air through this resistance.
I've since discovered that a pair of nexxos 12V fans stacked on the "pull" side work just fine and, at 12V are under 20dB (my estimation). If you undervolt the fans a tiny bit (either with a fan controller, a resistor, or a rheostat) they get (surprisingly) quite a bit quieter. I can't hear them over my disk drives (quiet seagates).
If you decide to go this route, I'd suggest buying a heater core for a '71 mercury montego (fedco 2-224), about $34 at partsamerica or rockauto. Then get a coolingworks "coolshroud" (? I may have that name wrong) - about $11 When you stack fans, put something between them. I use a hollowed-out fan frame (easy as I had a dead 120mm fan I hadn't thrown out), but you could just as easily space the fans on long screws (or threaded rod) and just wrap the outside with duct tape.
Oh - and if you don't mind using AC fans in your case, ferdb has found some 120mm 240VAC fans, that, when run at 115/120V perform better than the nexxos ones (quieter and enough more pressure that they likely don't need to be stacked). (FWIW, he's who put me on to nexxos fans as a possible quiet solution...)
Anyway, before going any further with this, why not cut out a piece of paper, say 6.25"x7" and see if there's room for that in your case. If there isn't, there's no point in thinking about these right now... (but remember the nexxos fans as they'll be quiet on whichever radiator you end up using)
