you need to buy a CDI (Rapair) ESA module.

Welcome aboard !

If you go with a v-6 or v-8 you need the correct esa or wire it like a merc.

The ESA is the sum of the two switches and their interface with the shift cable linkage, cam lever arm unit, etc.
In answer to the question, if the ESA unit from the 3.0L will adapt to the 5.7L shift cable plate arrangement, then you may be able to make it work.
The main shift cable, the lower shift cable and how this operates the drive shift mechanism, won't even know what engine it's attached to, unless you tell it!
However, it may be easier to pick up an ESA unit from a 5.7L.

It's the change from a kettering ignition system (contact points) to electronic triggering that causes the need for the ESA module kit.
Or..... like said, re-wire this similar to the Merc SI system.

I see that we left the back door unlocked again!

Really ?, Who in the h*ll calls them that other than you.

Somebody found a old tech page from long long ago.

Nope.... no old tech page required.
I cut my teeth on these things back before we began to bastardize the correct terminology.

BTW, Charles Franklin Kettering working with his small group in a converted barn in Ohio invented the standard ignition system (Kettering ignition). You'll find conflicting information as to the year when he invented this system.
His basic system was used from the early 1900's to the time when electronic trggering became the norm.

From one source:
The Kettering system used a contact breaker, known as “points”. A condensor across thes points (condensor = capacitor, British usage) which switched the +12V through the High Voltage or ignition coil to negative..... yada yada yada, and so on.

You can possibly see why the term "points" or "contact points" became the mainstream language term.

In 1915 Kettering invented them, But, They were never sold or known as Kettering points.

I repaired cars for over 44yrs and never heard them called that.

I'm calling bullsh*t on that one. :rolleyes:

Do you have a particular angenda or point to be made here?

Forget it lets move on.
