Sorry, Ma knew. Copper. 400 to recore. Nice and cool. Green. Clutch. Shroud. All the things Ma designed to keep it cool still work for me. I will sit in a Parade in Reno at 107 degrees with any of you. With the AC on. For two hours.
The specs for the 67-69 fan shroud say it is for a 16" fan (Part # P2785434). I was wondering what Mopar fan shroud you are using. Also, what's the diameter of your fan?
I have an 18.25" fan and looking for something that will bolt up to my aftermarket radiator. I have a 68 RR with 440. The fan shroud for the 70-73 b body has a larger diameter opening.
