Review on Black Urethane Radiator Isolators for GM Style Small Block Engines, Prothane 7-1711-BL by Richard Rob

Revainrating 5 out of 5

This is what I needed to install an aluminum radiator.

This is what I need to install an aluminum radiator on my 73 Nova. The small rubber nipple is in the right place for the Chevy, although they are more "universal" and slightly longer. I tailored them to my purpose.

Pros
  • Engine Cooling and Air Conditioning
Cons
  • Zero
