Thanks Ray. I had a hunch the new rads with (almost) stock look would be the best option. Do you happen to think the rad in my pics would be original to a big block car? It sure seems small. Also, with new rads, would I need to specify it as for a 4 speed car? Something tells me I wouldn't. I'm not sure what the difference is between auto/manual rads even is, but again- the more correct looking the better!

The automatic rads have a cooler in the bottom tank and two female thread ports for the cooler lines to go to, so the difference is visual. To be authentic you would certainly want to have a 4 speed only rad.

That sure looks like the original radiator. The biggest rad you could get in 67 is a 3 core, no 4 cores in 67. That one is probably a large 2 core. I have a couple BB 67 4 speed rads and they look the same. Is the ID tag still on the rad? Should be by the upper rad hose.

 

I checked and no tag anywhere near the top rad hose. I did however notice a code on what may be a bracket on the driver side. Parts Catalog lists part 3007704 as "1966/ All AT with 396 engine- exc HD rad- exc factory installed car cooling". It also lists same part number as TH with 390 HP 427 engine. So I'm taking from this that the rad is a 1966 rad for TH400 car with big block and no A/C. That might make sense, since notes I have, made by some owner previous to Elroy and I, state that a 396 and TH400 was pulled out of a Grande Parisienne and put in the car at some point. So that rad could have very likely come from the same GP. The 396 in the car has casting #3855961 and coded T1220IAR with no VIN stamp BTW. This might be a valuable block (1966 4 speed) to somebody here when I put the correct 351 casting 427 back in the car. But back to the rad- looks like I should have rad part number 3012411 to be entirely correct (since my car didn't come with HD radiator). Assuming I'm correct, that rad might be hard to find? There are other hard to find parts I need, and since I'm AT LEAST a year away from being prepared (in terms of finances, expertise and parts) to start a full restoration- I might as well keep my eyes and ears open. From what I've learned here so far, it would seem the best of all worlds solution is the correct 3012411 rad re cored with high efficiency aluminum core. One more thing..... The 04 above the part number- would that be a date code?

For my 70 Parisienne that I put the LS6 in, I used a 4 core radiator from a big block a/c car.  I had it recored with a 3 core high efficiency a couple years ago, and I think it was $600 - $700.  I had asked for it to be done as a 4 core (same as on my 70 2+2 convert), but they don't do that anymore.   It has the large top and bottom tanks required to be a 4 core. 

I have a 3 core in my 70 Laurentian, it has the same top and bottom tanks as a 2 core.   So if you are looking to have yours recored, I suspect you may be able to go to 3 core high efficiency with your stock tanks.
