Also, keep in mind that an electric motor is both easier to shift clutchless, and easier on the synchros over time. That's because an electric motor has less rotational mass than an ICE, and no pumping resistance to overcome, resulting in far lower resistance for the synchros to overcome as they equalize the shaft speeds inside the transmission.
It still takes time, though, and 2 seconds is a long time to wait for the shifter to fall into place if you aren't used to it and planning ahead.
Also, if you delete the clutch, its critically important that you get a later Saginaw Corvair 3 speed with synchromesh gears on all 3 speeds, not one of the earlier units with synchros only on second and third gears. You'll only be able to downshift an early gearbox into first at rest without grinding it, making it unsuitable for clutchless operation.
With a DC motor, a clutch is also a safety feature, as DC controllers can fail shorted, which results in full power that can't be turned off. If you can't pull in the clutch, you'll have to break the high voltage circuit under max current to stop the car. You should of course have a system (contactor, "Oh, Scheisse" switch, etc.) to do that anyway, but the clutch is actually more reliable and easier to think of in an emergency. AC controllers don't fail in full power mode, so its not an issue is you go AC.
Lastly, I don't think the Soltion Jr. (or Curtis) controller is going to be satisfactory with a curb weight over 2600lbs, and a gross weight well over 3000 loaded. The extra 50% more current of a Soliton 1 is going to be very useful getting your car moving. Once you go to 1000A, you'll be much better off with 180Ah cells, which won't be nearly as stressed or sag as much as 100Ah cells at the current the Soliton 1 can draw. (5.5C versus 10C with 100Ah cells.) If you want anything like stock performance, 650A is going to feel slow.
