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.

Chris.

No offense but I seriously doubt it. If we start stretching the “anything can happen” tune to comparing Pontiacs to Chevelle or a 360hp to what would be in 375hp ( 4 row wide tank ) to convince ourselves of things that we really don’t need convincing on., we open up a hornets nest for every guy who wants to claim his car is all original and God knows we have enough of that out there.

A 66 SS 360hp 4 speed car would not have a 4 row rad. Could you order one? Sure. But not something that would come standard. It would also be very unlikely to get an Automatic Trans installed in a factory 4 speed car. A carry over Rad would be from a 65. A small block. The 4th week of October was by no means EARLY in my book. I know nobody is claiming absolute here but we have plenty of heavy documentation on Radiators in 66 SS Chevelle. They aren’t interchangeable with Pontiac and not even close to what a 65 Chevelle Rad would be like.

Anyway. Sorry to get off track on your great post Bruce. Just adding my experience to the mix.

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.

Note the Upper Tank code in your photo.

Letter G That’s a July rad. Probably of 67. Over counter replacement. Hence the filled/capped holes.

Side of Rad. on strap. Driver side. You will find a stamped letter code also. Likely F G or H
Example of letter A here

Found letter code on side its an F

Looked today for build/broadcast sheet no luck but I did find this tag in springs of driver side bucket.

[MYSTERYCHEVELLE]

Awesome. Interior Broadcast Sheet!!

I’d need to see it up close to decipher the hand written codes I can barely see but no matter. It’s a Birth Certificate

[Brucebodyman]

I see 13817 in the upper left corner. You can actually make it out better in pic than in person. I’ll try to get better look and write down what it says.

[Brucebodyman]

Within that orange circle to the right it looks like 7_3 S can’t make out middle letter cuz of spring imprint. But interior code is 763 S which is black bucket with headrest code
