LS 7 Motor LS 4 Heads on it.
I recently removed my new Aluminum rad and the manufacturer is possibly going to replace the tubes with Extruded tubes for greater strength and better cooling (from NasCar technology) he said. But I do not know if my motor has or SHOULD? have a steam tube, as they told me there was NOT a fitting on rad currently.
