Documented?  Some of my work is in the archives.

Uh-huh.  Well, it's like buying a car that needs paint vs a car that
needs total restoration.  The guys with ambition think they're all the
same.  The guys with experience recommend starting with the paint job
car.  It's easier and faster to finish, and you will be enjoying your
work sooner.

Hey, don't be dissin them Q-jets.  : )  

'Sides, all things are possible, it's just a matter of time and money.

You could make something like this.

What!!  No 165/730's?  You're kidding??  The 165/730/727 have been
used on more 2.8/3.1 cars than on 8 cyls.  Plus they cost less if the
yard doesn't think it's a Camaro or Corvette computer.

Well then, what are you doing wasting time reading?  Run out and buy
some parts, bolt 'em on, see what happens.  That's how a lotta guys on
the list were working back in the early days.  Then when things don't
go right, figure out why.  This 101 stuff makes things waaay to easy.
