Champion radiator for ~500hp small block??

I agree RRR. The aluminum radiators do a great job. You do have to admit that it gets old when they say it will fit. Yes, after modification. I had to modify the 26" Champion in my Road Runner, the core and brackets were too wide. No room left to modify the radiator, modify the radiator support. We just have to know what we are getting into.
Good luck with your choices!
