I currently like the idea of keeping my z as stock as possible.  I’m no purist.  I preffer making things better if it will prolong the life of the car, or if it’s a safety item.  My question is, should I replace the original radiator, or just have this one boiled ? 

 

 

There are lots of Zs out there using the the stock Rad with no problems...

Thank you. 

My '72 was leaky so I went with a '78 radiator with a ZX full shroud.  Runs nice and cool.
