Understood, but what else is missing? The complete engine with gearbox and diff weighs 430-460lbs. If the half-shafts are gone, that's probably another 30+ lbs or more each, so something north of 500lbs is gone with the driveline. Is the interior complete? Got all the glass? Spare and jack?
If you're at 1750lbs, that's great, but you'll need to add back the things necessary to operate the car. Since you don't have the heavy half shafts, you can save some weight with aluminum replacements without thowing out perfectly good parts. If you don't have seats or they're shot, light racing buckets would save more weight. All in, I still think you're going to have over 2000lbs of glider in stock trim. If lots of parts are missing lighter replacements are not such an expensive upgrade. Drag racing seats would probably cost less than restoring a much heavier pair of Corvair front seats, for example.
I'm with Miz on the drivetrain. A Corvair is just too heavy to go direct drive without a big motor and very high amperage- and the transmision options are very good for your application. The Saginaw 3 speed is robust and has good enough synchros that, (provided you weren't intending to shift quickly or really go for the very quickest acceleration,) you could go clutchless, even with DC power- but drive somebody else's clutchless EV first if at all possible. Its not for everybody having to wait a couple of seconds to change gears.
Anyway, time to talk about range. Let's say you can get it on the road at 2750lbs (Glider at 1950, motor, high and low voltage wiring, controller, adapter and charger all in at 225lbs, and batteries and boxes at 575lbs- which is 45 180Ah cells.) You could expect the car to consume 275Wh of energy per mile, probably a little more because its not particularly aerodynamic or small, and the stock bearings are hardly low-drag modern units. Call it 325Wh/mi worst case.
Anyway, your 45x180Ah pack is rated at 25,920Wh, of which you want to use only 80% regularly to maintain battery cycle life, so you'll have 20.7kWh full to empty. At 325Wh/mi, you'll have nearly 65 miles of range, and if you only actually use 275Wh/mi, you'll have an honest 75 mile range.
That would make a dandy EV Corvair, but the components are going to cost nearly $16-18k, of which over $11k is batteries.
