Looks good! I'd love to know how this all works out..

Any reason to go holley sniper + standalone auto controller vs. Holley Terminator with the transmission control option?

Did you swap to an electronic speedo or get a mechanical speedo output for the 4l80?

Any modifications needed to the column shifter?

I had the Compushift left over from a previous truck. I used a Lokar shift rod and put an OD lens in. The standard shift rod was to short so i had to by a longer rod. i changed all of my gauges to the Classic Instruments. I had them put the red needles in so they look almost factory. It is going to work out very nicely. i have about 200 miles on it. Next will be an Eaton Posi and 3:73 or 3:42 gears. i am leaning towards the 3:73.

Are you working on something like it? There are a lot of little things i may be able to help with. Like motor mounts, headers and such.
