26 inch ECP in a 68 Dart

I say that because of both what I have read and seen, first hand. And no, I don't plan to run one. I've never seen problems with Be Cool or Griffin, yet there are hundreds of threads online about chinese imported radiators that don't cool well.......whether champion or whatever other brands there are. Lots of people have great luck with them. "I" will not take a chance on one and "I" will not recommend them.

I have also not tried eating dog crap, but I don't recommend that either.

Here's an entire thread about griffin radiators not fitting properly, including some of their "direct fit" radiators that start at over $600 and are supposed to bolt in, but still required modifications.

Griffin Rad fitment issues

Griffin's direct fit radiators are $600+. Be Cools direct fit radiators are $700+. Their cross flow radiators are cheaper, but they're universal radiators and need mounting, and then you have to figure out new radiator hoses.

So no, griffin and be cool radiators aren't 100% problem free. And for 3x the cost, you'd think they would be. I'm ok with making a few small changes to the mounting holes if it means saving $400 and still using stock hoses.

Regardless, the OP never asked about Be cool or Griffin radiators. Probably because a $600 radiator wasn't in his budget. And since you've never used or installed a Champion or ECP radiator, I don't see how your comments are useful here. I've read a lot of those horror story threads about champion radiators, and I read a lot of them before I bought mine. Some are legit quality issues with champion, it is a cheaper radiator and they have some QC issues sometimes. And some of them were replaced under warranty by champion too. But some of them have more to do with inadequate fans and cooling systems outside of the radiator too. Put a crappy fan on a Griffin and you'd have the same problem.
