So you don't care if you overflow antifreeze on the road? Nor are you concerned that the coolant that flows out isn't likely to be replaced!
The overflow container allows the engine to accomodate high momentary temperatures and not lose coolant so it is available for the next heat cycle. Eliminating the overflow container would be a serious loss of a protective device for your engine.

Year model you are talking would be nice.

If you are talking about a late model C4 then the "big tank" is the thing that holds the pressure in the system
Only on early cars is it a catch can

I'm not sure of this one owns a Vette. Appears he may just want to dress up and show.
His list of mods include: "air freshener (: and tach"

It's a 95 LT1 out of a vette, but I bought it swapped into a silverado. The 93 pace truck to be exact. I think it's the original holding take for the over flow from the original engine.

Does your truck radiator have a cap to keep pressure in?
If so you can delete the LT1 header tank and just use a overflow bottle off the radiator
