Re: Overdrive transmission for our big blocks

[Wakeman Massie <wakey@xxxxxxxxxxx>]

This diplomat forum entry has basically everything you could want to know 
about the 500's, 518's - where they come from, which ones you want to do, 
not do, etc.

http://www.dippy.org/forum2/index.php?topic=231.0

Also, I found this site very helpful when I was doing my swap - not to 
mention they have probably the biggest selection of 518-related stuff I've 
found.  Scroll down.

I'll send more later on the particulars of my install.

Actually please tell us ON list...inquiring minds want to know!!!

I had heard that the A518 install was easier in a B-Body as the tunnel
was larger, and all you basically had to do was put the O/D unit on
the back of a 727 (because of trans mount location), and install a
couple of well placed dents in the floor pan. Someone please correct
me if I'm wrong!

Also, what all are the A518's found in? I was thinking about doing
that swap eventually in the 'vert.
