Has anyone done this? I would love to talk to someone that has. The 5.7 vortec is coupled to a 4L60. How did you do the speedometer? I have tons of other questions. I have a complete '84 S10, a running '97 suburban with 5.7 vortec, and a '53 3100. I am planning to start this project this winter. I would love to chat with folks that have done this before. thanks
