Champion radiator for ~500hp small block??

The OP is looking at a CC281B out of a Chevy Impala, for a '73 Cuda.

Yes, and I think we've made it clear that we have no idea if that one will fit or not.

And we've also included part numbers for a radiator that's like $200 new that will work for a '73 cuda, in addition to showing it will fit an A-body as well. So?
