67 Cuda Cooling

2.5 years later and I haven't done a thing with my 67' Cuda FB, other than start it and drive it rarely and confirm it is still running hot in summer and running ragged in the 30-40mph range. I was considering buying a 3-row Champion radiator to replace the non-original 68 318 high altitude radiator.

Anyone out there wish to chime in on Champion? If I go with it, should I buy the shroud too? I have that original 4-blade non-clutch fan so I guess I could replace it too...suggestions on where to buy that?

Thanks!
