What headers did you use? It doesn't look like you had to mess with clearance at all, so I am curious which ones you selected. The closest I've seen are the 2010 -2013 F-body headers.
What transfer case did you use? How did you hook up your speedometer? Did you use the factory sending unit for TBI setup? What are you doing about the voltage, oil pressure, and temp gauges?
Thanks....Enjoy that power!!
