I have a 70 challenger finally giving it some attention. 440, going to do a serpentine belt set up with A/C and P/S

I'm looking for opinions on Aluminum Radiators and fan set ups
 
Big block or small block? But it really doesn't matter. There are lots of aluminum radiators out there now. Just get one with the upper and lower hoses on opposite corners and think 2 row over 4 row. I'd try to find and spend the extra money on one that looks like the original factory type tanks.

Some love using electric fans, but I still love the old asymmetric 7 blade fan with a clutch. Regardless you need a fan(s) shroud for it.

And run a 195°F thermostat. That temperature setting seems to work best with our Mopar.

Thanks guys. I'll repost in the correct place. And I'll do some more digging on style of tanks and such.
