A remaining few Q's:

(1) Is the injected 302 still compliant (e.g., a US import?).
Yes
(2) Also, how tough is it to change the engine mount setup that I have already there from Warwick Harrison to suit a 302?
Would have to ask Warwick, as it will be harder now the body has been fitted.
(3) Is a well-sourced 302 likely to be ready to go, or is it necessary to do a substantial re-build (I know that one might do that eventually), other than renewing all the clutch components?
They seem to have a great longevity, if you get a good one, it will last you well.
(4) Is the gearbox with it a robust one - decent synchros and reasonable shift action?
T5 is a great gearbox to drive, not as strong as most though, so will only handle hard abuse from a mild 302w engine
(5) Last with the Harrison 4.3 rear end is the standard 302 'box going to be out of synch?
If you decide you don't like it, you can always change to taller 3.7 gears. Most Harrison owners with 302w & T5, run 4.3 gears and are happy. WKB can show the way to 3.7 upgrade if you decide to.
