In the name of turbo science, would you please post a couple of
pieces of data for us now that you've got the end caps off? I'm
thinking someone (who me?) might take a stab at estimating the
efficiency of the stock IC if we had good numbers for the
height x width (frontal area) and thickness of the stock IC core
and how the frontal area is apportioned between the bottom
and top sections of the 2-pass layout. 50-50?  Also, knowing
the inside dimensions of the internal tubes could be helpful for
estimating pressure drop. TIA.

Re end tanks: Like Graydon said, have aluminum tanks welded
on and your cares will be over. TAP does this on their ($$$$)
IC conversions. Others have done it as well. Maybe some
of Spearco's standard cast parts will fit the bill. Otherwise,
someone good with aluminum sheet and tubing could handle
it.  The second solution would allow you to install baffles
to force good flow distribution.  Best regards,
