Has anyone tested these 4.0 headers and carbs from Cliffords?

If you are worried about a solar flare or other electronic destroying occurrences, fuel injection is NOT the way to go. Carbs are simple to set up and their functioning can be figured out without a code reader or electronic meters. In short even I was able to rebuild and re-jet a carb. They work well up to around 10,000' plus but will require re-jetting if you are trying to run from sea level to the heights of the rockies. Suspect proper jetting for Denver may get you anywhere in the surrounding mountains. Carbs are pretty reliable running the life of the '60s era engines without much maintenance once set up properly. They don't require failure prone ancillary electronics like O2 sensors to work properly, just reasonably clean fuel.

Carbs do not give as good gas mileage as fuel injection and don't automatically compensate for altitude differences. They don't monitor the fuel/air mixture as minutely as fuel injection so don't result in as good gas mileage. A rather big thing in today's $5.00 a gallon gas and going higher if Uncle Joe and/or his minions have their way.

If I was to go adventuring into very remote areas or was a prepper would consider carbs. For the rest of us, fuel injection works and there are enough people around who can fix it if something goes wrong. AS far as those claims of additional power, think they are largely BS. Dumping more fuel into an engine without increasing the Oxygen is just a waste of fuel. To get extra power you need additional engine mod's like a hot cam, larger diameter cylinders/pistions and/or higher compression. All of which add to the cost.

What if you are worried about a Chicxulub asteroid impact type of event? Which fuel system IS the way to go?

Guess you forget about coils, points, ignition modules and the rest of the crap on a gasser Kim J can smoke with a emf bomb. The only true emf proof engine is a diesel with a cable operated fuel shut off or one that can be converted to that from a solenoid. Far as clifford goes, buy one of their cams and mic the lobes and have a good laugh, or cry is more like it. Been there seen that.
 
My major issue with EFI is the "E" part of it. Straight mechanical FI is pretty bombproof in more ways than one.

This won't work, will it?

If we have a emf or other electronic destroying event, your Jeep running will be the least of your worries!
 
Why would anyone convert their 4.0 from fuel injection to carbs?

And 25 mpg from a 4.0 TJ? Don't be so obtuse as to believe such an outlandish claim.

If converting to carbs resulted in a ~10mpg improvement in fuel economy I think it would have come that way from the factory :ROFLMAO:
