Hi Ken,
Thanks for your input and openness on the subject of weight compromise.
The
decision was definitely a compromise and one that I struggled with.  The
extra weight is a concern but one I am willing to accept due to the ease
of
construction. My welding skills are rusty and I've never even attempted
to
weld aluminum, so I not really enthusiastic about testing my skills on
such a
critical part.  As far as being tuned for my desired RPM,  I don't
really
know at this point.  I figure I will invest the two afternoons that it
took
to modify the stock manifold and then just run it on the test stand and
see
how it does.  If it does not perform well, then I'll start on PLAN - B
at a
later date, having only lost 6 hours of time trying to make this one
work.  I
can still try to do come tuning on the upper 1/2 of the intake manifold
by
extending the length of the runners.  This part should be relatively
easy
compared to trying to fabricate the lower portion of the intake
manifold.  I
am contemplating cutting off a couple inches of the lower manifold ( the
part
that sticks up above the injector ports ) to decrease the height, but it
looks like it will fit into the cowl without this.  I'll keep you up to
date
and post new picks as the project progresses.  I've attached a pick of
the
engine with some of the components loosely hanging in place so I could
better
see the spatial relationships.

Sincerely,
