Is there a code breakdown for the big block/Stage 1 cars?
They are different for AC and non
IA code tanks are the most common. They appear on most.
"Is there a code breakdown for the big block/Stage 1 cars?"
It takes a while to figure out the correct rad for a particular car. It depends on the options, year, and sometimes when it was built. There is at least one of the 70-72 years where the "Radiator Code Sheet" was changed in mid production. You need to figure out if it's a Stage 1, or a GSX, and then look at the sheets.
Even then you can still get the wrong answer. The codes for the 71 GSX's do not match up with what was installed in the cars, at least not for the small block cars. I had the original rad (correct radiator with the tag, hose clamp, date code, etc.) in my old 71 350 X, and bought the car from the original owner who swore that it had never been changed, and it did not match the sheets. (The car still had the original hoses on it when I got it.)
Then you get the issue where they may have been short on a certain rad and installed a substitution...often a larger one.....or where different plants stocked different rads.
Or maybe the car was ordered with heavy duty cooling. In that instance a 350 non-AC car would have come with the largest radiator available, which would make it appear that it had an incorrect rad, and one that should have come with a Stage 1 or GSX with AC.
There are simply too many variables to do what you are asking.
Thanks for the explanation.
I'm surmising that there's a good chance the Harrison in my car could very well be the born with, 3 row radiator.
If the date code on the rad matches your car then it probably is.
Perhaps I missed that but where is that located?
If you look at the pictures that James Weinman posted earlier on this thread you will see a small raised letter code between the 2 code letters "CF" for the tank. In his post it is an "A", which means it was built in January. I have a breakdown in my book listing the codes for every month.
I'll have to look at both the tank and the book when I get home.
Brett remember if you can’t find it probably no one else will either.
Good point! Haha
Looks like an April code - which would be either too early or late for my car - but to quote my radiator guy when I had it tested last year: "It's not the best radiator but it doesn't leak."
One is. OI
I paid over $350 to have my radiator redone in copper. Everyone just wanted to sell me an aluminum one for $125. Keep those tanks.
Well they're gone....got $90 for seven radiators. I know one of them was the original for my 70 x Stage 1
Too bad you didn't list all the tank codes on here. I'm definitely sure someone could've used one.
how do you cut the tanks? i have 3 or 4 350 radiators laying around.
