Most motors can take as much heat as the TB itself. I'll probably be testing how hot it gets, although it will be 40F outside.
The issue you'll have is the motor they used. It will almost certainly be a stepper motor, which requires a small controller (DIY for under $50). THe cheap controllers usually will do one step at a time, $$$ units can probably to enough steps for 90 degree swings and be programable. THe issue is you get into complicated electronics and lots of money. THe truth is I haven't thought of anything cheaper than this, and Stephen Hawking IM's me for support.
I could probably make another for a decent price, but it will have a thin flange for the TB - and I'd probably need to grab a HMT sponsorship to say YES. You could actually pick up the TB and motor yourself to make it better. ALL EF wiper motors are the same part #, and Ford made this same TB for many years on many makes of cars.

All obd1/2 LS TB's are 60mm, so with the stock exhaust before it, it should be fine. It doesn't really matter, since its just the very restrictive muffler that causes the most losses.
I used the front EF wiper motor (all 88-91 EF's use the same part #), but almost any wiper motor should work. Some companies use circuitry in the newer cars in the motor housing to always return to the same spot, and aren't reversable, so be wary of other sources. Since this motor rarely dies, there should be lots of them in junkyards. The best part IMO was the dual speed ability of this motor.

Actually I got a manual throttle/choke cable at work, one that semi-locks open & closed. But I just decided to go *****-out and rig this up. Half my time was spent getting the damn limit switches working juuust right.
