yes it is. I have aloas heard that it is easyier to switch new motors into old cars if you use carbration but if you have the computer and everything the throttle response you get from EFI may be worth it.

Without the shop manual, this could be a daunting task. I actually did this on an old V6 Astro? van with TBI. All I had was the little "Clymer" manual, which is not a great help. 'We' were going to adapt this system into a buddies V6 powered Jeep
I removed the harness from the car--which was junk, removed the in-tank pump, the distributor, throttle body unit, computer, etc, and laid them all out with the harness, on which I marked the connectors.
Then, I simply untaped the major harness until I'd eliminated everything except the interconnects for the EFI.
There are pitfalls, though, the newer the rig, the "worser" There's things like transmission controls, hookups to the speedo unit, etc.
Without a shop manual or at least a complete diagram and a Cymers, this would be a job.
If you don't understand electrics, it would be wise to buddy up to some local "geek" who does
Even if you decide to eliminate the EFI and go "carbs" what will you do about igniton?

Hey,
I'm stupid. But, what I see is two things.
You need to totally access what your removing and make sure you get it all from the truck to support the operation of the late model hemi. But, remember that new hemi is just an air pump that compresses a mixture of fuel and air. It would operate very nicely with a carburetor, pointless ignition and a decent transmission behind it.
The new engines are not magic, they are the same as the old stuff, there just covered in gadgets that the dealers can work on and you cant. Strip it down naked, and use old school techniques and you'll have a screaming monster that will perfornm well.
