So I busted a hole in the factory radiator the other day. I've needed to replace it for a while but now it's absolutely unavoidable. :P
I'm looking at Champion Radiators and the site says their 22" 2-row radiator (EC2374) is good up to 375 hp. I would be surprised if I'm much over 200 (but I've never been on a dyno and can't guestimate for crap)
Still unsure, I gave them a call and the guy on the phone confirmed that for a super mildly built 318 street engine, it should do just fine.
Now just to be absolutely certain... Is there anybody here running this particular radiator?
Info on my car: '72 Dart Custom Sedan, super mildly built 318, a904 with an external cooler.
