NG 2.3 in a 4000q?

[Richard J. Andrews]

I found a complete NG for $200 locally and would like to transplant it into
my 4kq in place of the wornout 2.2 JT engine.
If i get the fuel distributor and retain my original ignition system will
this setup work in theory? or do I have to rewire all the Fuel injection?

Thanks!
