I’m not sure this ‘66 SS still has it’s Factory installed radiator?

On a high horsepower such as this car, I would think it would have the wider 4 row radiator, as that is what Pontiac used on their Tri-Power 360 HP for the 65-66 GTO’s.

Many of the 1965 360 HP with manual transmission GTO’s from the factory had these slotted brass plugs in the bottom tank.

Photo below (difficult to see here) shows the plugs in the tank on a 15160 mile 1965 GTO Survivor.

The “top” tank on this ‘65 Survivor had the radiator code stenciled in white paint.

The fact that this ‘66 SS is a relatively early built 10D = 4th week of Oct ‘65 for the ‘66 model year, it could have a carry over radiator from the previous year?

There is a member on this forum which owners a 4000+ mile GTO Survivor with the 360 HP / manual trans that also has these brass plugs.

Thanks for all that info. It’s hard to get across in pictures but lookin* at car it doesn’t appear that radiator has ever been out of car. It still has the original voltage regulator on it original coil etc. it just doesn’t look like it’s been messed with. But who knows.
