Alright, the question was......I already have the engine and tranny in and running and driveable. 5.3 with 4l60e. That ain't going to change. Guess I should have stated that first. Already looked at TheAliens build, and what a fine detailed build it is, Nice. I'm interested in just saving some money on the guages, since my guages all work as is hooked up the the 5.3, just not the speedo. Not interested in spending the money on the Abbott Xbox converter. Speedo's are a little over$100. Wiring is cheap. Also looking for a matching tach for the center hole. Anybody done this. Speedo and tach changeout only?

Thanks for all the replies.
