The difference between what we believed was a 2.73 to the 3.42 that we put in my wife's chevelle was night and day.

Not that we recorded mileage on the car, but it seemed somewhat the same and...

I did speak with Cold Case directly and as mentioned here above, you can in fact drill into the U channel which is hollow. So, I'll be doing that.

These cars are horribly undersprung as they were designed. Shocks that lack much in the way of rebound valving don't help that much.

Based on what you're saying here, I would probably recommend a...

You can go from as mild as adding a sway bar and upgraded shocks to the stock control arms and springs, to rear link type suspensions and aftermarket sub-frames.

Here’s a picture of the engine bay. You can see the straps that hold the upper fan.

They are just unsightly.

So it sounds like that top u-channel might be okay?

Drilling into the Radiator

As the title implies, can this be done? Obviously the end-tanks need to remain intact and sealed to hold pressure.

I'm asking more about the top panel above the tubes and fins. My fan shroud...

The sniper runs the fan in stall and crank?

I guess that would create a pretty easy test for the OP. When the engine is off and heat soaked, disable the fan in the ecu, then attempt to start.

You can try an insulating spacer under the sniper to help with that.

And the Flex-A-Lite Black Magic 180 for F-body sized radiators. This is what I use and it cools sitting still and at highway speed.
