That is correct, but again, K-02 or not K-02 does not affect the radiator size or whether or not the car got a shroud. And adding A.I.R. or HD radiator (without AC) does not affect whether or not the car gets a clutch fan. So both your statements above are correct regardless of whether K-02 was ordered or not.

Correct.

Bottom tank is the same as the medium size radiator for an automatic except the drain cock is in a different position. The code of the bottom tank is L O. The side mounting bracket has a C stamped into it. I believe this is actually for a 65 or 66, or 67 BB full size chevorlet as the core is actually 2" taller than the chevelle SS core. Anyone know what it is for sure?
If it is 2 inches taller than a chevelle I would assume it was an Impala unit, but I do not know for sure. Jeff

They are in the center of each tank facing the engine.

I found a tag soldered to the brackets (inside the "U" channel on the driver's side), with the part number and "Harrison"... I'll have to check again, but I thought I saw a code of "G 65" on the same bracket... The radiator is in the car, and i was checking with my flashlight...
With the "Harrison" labeled tag you refer to, perhaps it was a service replacement unit?? Please email me some good pics of all the stampings and the tag.

The unpainted 4-row radiator with finger guard pictured in the report is dated Feb. The unrestored 66 L78 pictured in the report (with 4-row with finger guard) is an 05D Fremont car. That supports that L78's got the big 4-row radiator without shroud as part of the L78 option, at least from March to June of 66.

Re: 66-67 BBC Harrison Radiator research report

Report above has been updated with additional pics, and:

1. Confirmation of VY build sheet code for the 3007621 radiator;

2. Confirmation that 4-row radiator with finger guard and no shroud was standard on 66 L78 (from unrestored survivor car);

3. Confirmation of VM build sheet code for the standard 66 L78 radiator (4-row radiator with finger guard); and

4. Part no. and build sheet code for small 67 L35 radiator further confirmed with close up pic of original tag.

Thanks to all who have provided additional info and pics - Jeff

Re: 66-67 BBC Harrison Radiator research report

Anybody know if anyone makes a close approximation of the "wide" 4-row?

I recall someone making repros without the "HARRISON" embossing... Not sure how close, or if they offer the wider tanks... Something for a driver, NOM...

Re: 66-67 BBC Harrison Radiator research report

Jeff: Pretty amazing detail. i do have a queston....i have a 67 L25 4sp car. According t the PP it is an a.i.r. car. it was delivered to Spokane Washington and did not have smog equipment other than the plugged manifolds. Would it being an a.i.r. car but not with smog equipment installed change it from the 3012137 w/finger guard VU?

I just installed a repro rad from muscle factory in Calif
it looks like orig to me and fits nd works perfect.
I had my orig factory Harrison on my 66 SS, but opted to put in a new repro so as not to worry about cooling system issues, and using up the Harrison . I will put it in box for future restoration as it need re cored.
