I dropped a used TII motor into a shell I had and the idle kept bouncing around 1500. In my case it was a fubar'd cruise control cable holding the throttle body open.

Is there some slack in the cable where it attaches to the throttle body?

Mine is doing the exact same thing, did you find a solution?

I'm not sure, but with a ported motor wouldn't you need some type of fuel controller?
