Wow. This is the motherlode! Lucky you.
We lucked out similarly with the ForkenSwift, in that whenever someone in the EV group in Ottawa was getting rid of their 6v golf cart batteries because they weren't delivering enough range anymore, we have been able to pick them up for not much more than scrap value. They still have value in a light car driven short distances in a small city.
We've changed packs something like 3 times now, and there's yet another "new to us" pack waiting in the wings. (OK, sitting on my garage floor.)

I will need speeds of 35-40 mph on the flat and a range of 8 miles. My commute is exactly 4 miles. Slightly down hill on the way to work and uphill towards home. I will charge at work just to make sure.
Will this work?

To put things in perspective, you can use the 48v/400A, 2070 lb ForkenSwift for comparison. It will
eventually get to 60 km/h (40ish mph). But it's slow accelerating above, say 40 km/h. 0-50 km/h on the level takes roughly 20-25 seconds, flat out.
If you love your old Volvo, then go for it. You'll just have to compensate for the added mass with more batteries/higher voltage & more energy consumption.
Where to look for forklift motors? Call some of the forklift service places near where you live. That's where the ForkenSwift's motor came from.
