You can leave the LH2.2 there, thinking that it is talking to injectors that aren’t there.
If you are going down this path, then I would suggest getting a 123 Ignitions distributor and ditching all of the original LH/EZK modules and wiring.
Be aware that the Webers are not legal in any state. If you ever need a RWC, you will need a “generous” inspector and if you are ever pulled over and asked to pop the bonnet, you will be defected.
If it was a 240, you might be able to BS your way out of trouble, but I can’t see how you’d be able to do so with a 740.
