That's cool, how did it go? Drive good or are there more things to address?
The car isn't registered or insured so I only drove it up the road a hundred yards or so. It really jumps when you punch it in first gear. I recall in my searches that it has about 180 lb ft of torque. I don't know how that compares to the 2.8. I also found that the 3.1 was rated at 140 hp, just like the 2.8, but that was with aluminum heads. I don't know what the hp is now, with iron heads but it's probably less.
It had a pretty good lope to it, so I contacted the original owner. He said it had a stock cam, so we're guessing it's just that the ECM has to relearn after the car is driven for a bit. It is running a little rich.
It even has AC, now.
