Option 1: Switch it to Carb. Edelbrock makes manifold for that era engine to run Rochester or Holley, Get new, normal, EFI distributor, use your intank pump with regulator to 6-7 PSI and plug/abandon all the sensors. If your tranny is computer controlled, switch it out, it may not be. The fit, mounting, etc is regular stuff. As Smith says about money, this still will be money. Option 2: If the Burb runs so great, leave it alone and sell it and buy a carb engine that runs good with whatever tranny you like 700R4 or SM* or T5. 67-87 is good.
