For my S-10 V8 conversion I moved it from the block to a hole I drilled
and tapped in the motor mount.  The JTR swap manual said it was fine,
and as far as I know it is...

If yours has an ALDL connector, you can pretty easily make your own scan
tool to read the data.  It's an unusual baud rate, 8192.  The problem is
decoding the data packet that comes out.  Seems like every ECM uses a
different size frame, and all the bytes mean different things.  There's
lots and lots of ALDL info in the archives, spend a weekend or so
browsing and you'll come up with lots of stuff.

Can't help with the rest....
