This has probably been covered a bunch of times. Ok big block 512. Noticed this weekend the fan and pump pully wiggle side to side about 1/4 inch or so. Not leaking coolant yet. In looking for replacement I found a ton of options. Not sure what I have now as I didn't build motor. This one has about 10k miles on it. Never had overheat problem except once stuck in traffic. Radiator (2949 055) has larger core from Glen Ray. As my wife says I always give too much info.lol. Anyhow what are you guys using or recommend. Thanks
