the Mancini muscle car rad sure looks like a Griffin.
Griffin furnace braze the tanks and coat with epoxy for vibration resistance.
i think the double 1 1/4'' tube unit is rated for 600 hp.

600 HP is what Mancini says for the Muscle Car Rad.

Another vote for Summit's rad. It has Northern Radiator stamped right on it, I paid 155$.




I'm not knocking your experience with the Summit radiator, but I have one in my 500+ hp Duster and in city driving, with the HHR fan, it will keep the motor cool at no more that 180 degrees..

However on the freeway for an extended period of time at 3600 rpm or while pulling a hill, the temp will slowly and steadily creep up to 210.. Thats where I pull over and let it rest..

I have thought about going back to the stock set up as it seems I never had a heating issue before going aluminum..

Last week there was an overheating post on another car with a Champion aluminum radiator and HHR fan - hot at speed. Based on pics it looked like the fan shroud was blocking free air flow on the roll. The poster removed the HHR fan and replaced with a mechanical fan. Overheating fixed. The HHR shroud mounted close to the radiator seems to block air flow when rolling. Its hard to beat the mechanical fan and matching shroud.

friend had overheating at speed.
rem'd the 7 blade clutch fan and shroud used a 20" 5 blade Dioplomat fan.
..problem solved.
i think the 7 blade clutch fans were discontinued on some early big blocks due to overheating..
