In a word- no, at least not as-is. These "E" carbs can be set up to run acceptably well for drag racing w/o a computer (limited in how much part throttle use it'll see, like driving back to the pits), but for a well mannered street engine you will want a non feedback carb.

The answer is, yes you can, but fuel economy and performance will absolutely suck. I'm somewhat embarrassed to admit that I've done this. The secondary side of the carb is not computer controlled, so WOT works fine, so long as you understand that the secondary air valves are limited to only open about 70 deg instead of the full 90 deg. The problem is the primary side. The primary mixture control uses solenoid activated metering rods that are pulsed in and out of the jets to control the mixture. Without the computer, they go full rich. The car will run, but it will be WAAAAAY rich at idle and part throttle. You cannot convert to the old style jets and metering rods.

Bottom line is, don't waste your time trying it - I already have.

The E4ME was a fair carb and wasnt excessivley difficult to set up.
Not an Ideal fuel control, such as EFI but not bad for the day.
The economy could be pretty decent on them along with lock up converters and such, provided the electronic control and sensors were all working.
By todays standard, they dont even make a good doorstop,
However, if you own a mid 80s G body and want it o pass emission inspection in Pennsylvania, you need to keep it OE underhood as far as emission devices go.

makes me glad I live in state that doesn't do emissions testing.. tho we REALLY do need a basic safety inspection.. some of the things you see here in Michigan will just make you shake your head in disbelief!
