[Merv and Sharon]

What a fantastic range of advice and information and I am sorry for opening up the 'political" dimensions on this issue! Price is not really a big issue for me now. I just want something that I am happy with. I have had many vintage cars and have never modified (well there were some heads and cams...) them in any visible way. I am kind of sympathetic for "heritage" reasons towards the 302 and they do seem to sound different (mostly down to particular exhaust systems probably). I really appreciate the values of the L76/LS2 and its modern parameters and also its compliance ease. I suspect that it is more difficult to set up.
A remaining few Q's:

(1) Is the injected 302 still compliant (e.g., a US import?).
(2) Also, how tough is it to change the engine mount setup that I have already there from Warwick Harrison to suit a 302?
(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?
(4) Is the gearbox with it a robust one - decent synchros and reasonable shift action?
(5) Last with the Harrison 4.3 rear end is the standard 302 'box going to be out of synch?

Apols for all the questions and the old ground for many of you, but this really helps!
