The following was a list compiled with the use of many V6 manuals and experienced mechanical individuals. Here is the list:
Rebuild on a 2.8:
Bore = 89
Stroke = 76
"Over = std
CC's = 2836
Liters = 2.8
Bore = 89.5
Stroke = 76
"Over = .020
CC's = 2868
Liters = 2.9
Result = Safe
Bore = 90

I hope that this information serves it's purpose to educate everyone in what to do and not to do with their rebuild.
