I have an idea.
I scrapped all the blazers I had.
Kept one radiator. (The rest were all obviously bad.)
Set that rad beside the old rad from my 88 troop.
Noticed that they are pretty much identical in capacity, and cooling ability. IOW: the blazer rad is not as tall, but is wider. Measure them for sq inch, and they are the same. The core is a two-row core, on both.
Like I said, they may look a bit different, but they are pretty much identical.
The only difference between these two, is that the blazer rad was made for an auto trans. I find it strange that one made for an auto trans, on a V6 engine, is the very same capacity as one made for a 4cyl with manual trans. But that is beside the point.
The troop had an AC cooler in front of the radiator.
It takes up almost identically the same room as the rad from the blazer.
Sooooooooooo....
I am thinking about putting the rad from the blazer, in place of where the AC cooler was.
Then run the bottom hose from the original rad, to the bottom of the engine.
Run another line from the top of that rad, to the bottom of the blazer rad. (Top circle, follow arrow to bottom circle.)
Then run the top hose from the blazer rad, to the tstat housing on the engine.

My thoughts here....
What do they do to a radiator to increase it's cooling power ?
Add rows to the core.
The best rad that I have seen, is a 4 row core, for a big block chevy. I am sure there are bigger and better.
If each of these rads have a 2 row core, then together they have 4 rows.
More capacity, and more cooling ability.
As for putting one in front of the other, and "blocking the air flow to the back one"...
Well, that AC cooler was doing exactly that, anyway. It was pretty clogged up, and the fins were not in the best of shape. So it was blocking
more airflow than the blazer rad will.
Besides, if you add two rows to the existing rad, aren't those two new rows, "blocking the flow", to the two original rows, just as much ???
So, bottom line... I am getting no different airflow to the stock rad, (Or in fact, better.), but I am getting cooling power out of what is now doing the minimal blocking.
End result, better cooling.
And if push really came down to shove, there is always the option to remove the stock fan, and put on a thermostatically controlled high flow electric fan.
Let the nay-saying begin.
