A lot to think about. Crate engine is peace of mind and has the warranty. I couldn't tow her home after I got her to work so I drove it home and kept pulling over to put more Lucas oil and motor oil about every 20 minutes. She made it home sounding not much worse than she already did. 1 hour trip home.

Sounds like the bottom end of the motor is wiped out. If you're considering rebuilding the 2.8. I'd stroke it to 3.1 with a newer crankshaft. The 3.1 crank from a mini van is stronger than one from a passenger car. There are casting numbers to tell them apart. You'll need the flex plate with it because in 1987 GM went to neutral balance crankshafts on the 60 degree v 6s. The flex plate on your 84 has a counterbalance weight welded on it. I'll have happy fiero flashbacks the rest of the day!

Another idea....
the 3.4 can directly replace the 2.8 correct? If I was to buy a remanufacturered 3.4 long block, would all the old 2.8 stuff bolt right up to the 3.4? Like the intake manifold, starter, water pump, etc etd???
