I plan on putting a 5.3 in my 93 shortbed k1500. I like the idea of keeping my 93 trans, just because there is nothing wrong with it and why try to spend the money and possibly have to modify the driveline and all that jazz. I'll be happy with getting the adaters for the flywheel and fabbing some new engine mounts. I started reading the sticky up top and have a general idea of what needs to happen. I am still foggy on the wiring. Is it possible to just use the GEN 3 cpu and get rid of the old one, or do you have to use both of them. And I know there is an issue with the speedometer and the drac but i cant really make out the problem in some of the threads. Do you have a thread on you build?
