I was doing some research and saw there is a conversion tail housing offered for the 4L60E trans to run a speedo cable:

I contacted a trans builder that I know who sponsors the Pontiac Drag Days bracket racing series out here, Hubbe's Performance
http://www.hubbes.com/. Hubbe says he can set me up with a 4L65E (stronger version of the 4L60E) and a torque converter for around 2K. I'll see if the 4L60E tailhousing/cable driven speedo conversion will fit the 4L65E and if so, I'll have that included with my trans build.
Still busy doing my research, when I'm more certain about what parts I need then I'll start ordering things.
