definitely food for thought as i'm headed in that direction though with a B motor. so it's a coin flip between upgrading to borg or figuring out "something else".
totally an aside, but what radiator is that? the install looks super clean.
MOP754:66-74 B,E Body Challenger Aluminum Performance Radiator MT 17x26 Inch Cold Case Radiators. Only minor mods needed. I wanted a big radiator for the RB motor.
Since I did not have any belts of pulleys for the pump. This was a great way to go. Plus I did not have to do anything to the engine bay, Well almost nothing.
