So I have finally figured out why I cannot keep my big block cool. After trying all kinds of fan setups, waterpumps, and even electric drive, I finally figured out why I have so much trouble keeping the 429 in my 68 cool. After replacing the aluminum with a used stock big block radiator I discovered that the aluminum radiator was not passing enough coolant. It is clogged somehow, most likely from sitting in storage years back. All this time I was assuming that there was nothing wrong with it since I bought it new and it was supposed to be great. I started to suspect that it wasn't efficient enough for the job and decided to try the brass radiator to get better heat transfer.
I just had to share this because I have struggled with it for so long. Don't rule out things when you are troubleshooting something just because you think it is good. The signs are there, test the parts before assuming they are good!
