I just ran across an article posted on Katech's website that I find fascinating. I knew that GM/Cadillac had developed a 60 Degree V12 that was based on a DOHC Northstar Variant. This Northstar engine was used in several Suburban test mules.
However, I never knew about a V16 based off an LS series engine design. Take a look http://www.katechengines.com/street_...20Portrait.pdf.

God thats old news... but cool none the less
GM actually entertained building an LS based V10 as well and at least publicly had shown a composite sample. The LS based 3 Valve truck heads looked promising too... but the valve train looked a little clunky. Imagine the way cool stuff that the public has never seen ![Happy](https://www.performancetrucks.net/forums/images/smilies/LS1Tech/gr_stretch.gif)

The Cadillac Sixteen concept was NOT based off the Northstar. It was based off the LS6. Years ago I saw some of the cylinder head and block castings in Katech's booth at the PRI show. It was very cool.
