If you are truly "high-tech" you will enjoy doing the swap and benefit a lot from it. The TBI isn't that much simpler than a multi-port installation because you must use
all the same sensors for it. Get the overdrive tranny fixed IMO... these systems are designed to work together. Do not cut corners on the fuel supply/return... you will be
really lucky if the tank can be swapped.
Do your homework before beginning ... plan ahead... there will be costs.
