Well, I'm about to find out.  My short block has been cleaned up and
balanced, a lightened flywheel and slightly hotter cam has been purchased,
and my head is at a 1500 specialist having its breathing attended to.  Add
a pair of HS4s and the UK exhaust manifold, and it ought to be better than
the original US spec, anyway.  I will certainly have spent enough cubic
dollars to go at least a little faster...
