Start simple... Flush the radiator. Burp the coolant. Change the rad cap. Change out the t-stat. Check for leaks, or weeping of fluid.
After which only a few remainders are left... Either a new radiator, a new fan clutch.
Not too familiar with the 88, but you've got to start somewhere.

Beast, check the coolant reservoir for cracks, there should be no coolant coming from the reservoir. If the reservoir is in good shape, take the cap off (when it's cool) then start the engine and let it run for a few minutes, that should cycle any air bubbles out of the system. Make sure your heater is ON full hot when you do this so that you get any air pockets in the heater core as well. Then report back. If that doesn't fix it then we'll move on to the next step(s).

That is a closed system with no radiator cap but a pressure cap on the pressure bottle. Make sure you put in 3.5 gallons of coolant mixture.
Trust me with the amount and you will not have problems with "burping" the system anymore.
This is why people burp the system because there is still some needed. Fill it slow and it might take 4 warm up cycles to do it.

If the coolant bottle cap doesn't seal properly, you will have problems. That's not to say there aren't other issues though. For about $10 you can buy a better cap from Napa. Part # 703-1396. Start there and see if there's any improvement.
