I converted to the four barrel for simplicity. For the time being I will run the carb, and see how it performs. I know it is notn the best for angles and tilts. My 88 has a 3.9 V8 with the same carb and ignition, and has managed 17 mpg with 4.70 axles and OD. I have run it over 30K miles without any problem, except a multiple rollover. I have two LR 3.9 liter EFI setups that I might play with for the future. The LR electronics are not known for their durability and seem overly complicated.... There is a somewhat nearby specialist shop that does a lot of MGB V8 and TR8 EFI conversions, using a simpler and hopefully more reliable electronics and sensors. I might drop by for a look.
