Pls help decode origina Harrison 4 speed radiators

[69gmmuscleluver]

I discussed 1 of these radiators in the past but never got a clear answer or even if anyone really knew the application. The first 4 core radiator I'm quit certain came from a 70 396 Camaro Z27 but I'm unsure how to positively identify. As for radiator #2, I can't remember where I picked it up years ago but it still retains the original tag with numbers. I tried to search for the numbers on the tag but was unable to find anything. If anyone has suggestions please help. Thanks again.

Don't know the exact application [img]<<GRAEMLIN_URL>>/dunno.gif[/img], but I can tell you how to read the radiator tag.

IA and AS are left and right tank codes. IA should be stamped on one tank and AS should be stamped on the other tank, if original tanks are still present.

66 is a code that dictates the size of the finned radiator core.

RK is a code that represents the whole assembly of the radiator. IA and AS tanks with a 66 radiator core. Also 66 is the code for the radiator assembly that will be listed on the assembly build sheet for the car.


If you still can't figure out this radiator I would try the below source. Robert is very knowledgeable about Harrison radiators and does a great job restoring them.

RK is the broadcast code. I think you mean that RK will be on the build/broadcast sheet.

RK = 3020004 69 Suburban 350 man - I assume it could be from a truck too.

Correct RK is the code found on build sheet (broadcast code) not the 66 (core size code).

Looks like I got caught sleeping in class again [img]<<GRAEMLIN_URL>>/shocked.gif[/img]

What's the part number stamped into the RK tag in your last pic,where the tape measure reads 29&quot;?..It's too faint for me to make out here,even when I flip it.
